This graph provides a great overview of the amount of time spent on different parts of the project. Parse a text file; each line follows the following format: YYYY-mm-dd HH:MM X minutes - (Category) Description. Create an image that can be easily added to a webpage. Hovering on a particular category and date should show the description. Follow the styling and fonts closely. Use the material gruvbox palette instead of those used in the image for category accents

I need to build a script that reads a time-tracking log file and generates an interactive calendar visualization with a dark theme, rounded styling, and diagonal splits for days that span multiple categories—similar to the reference image but using Material Design principles.
Since there's no input file provided, I'll write the Python script to parse the expected format and create a demo SVG with sample data to show how it works. The SVG will include native browser tooltips via title elements for hover descriptions, making it easy to embed on a webpage. For the font, I'm going with a humanist sans-serif like Lato with a fallback stack, using the light grey text color from the Gruvbox palette. The visualization itself uses a near-black background with small rounded squares arranged in a grid—each about 34 pixels with 6-pixel radius and 4-pixel gaps between them—with day numbers across the top, month labels on the left, and year separators when the calendar transitions between years. For days with multiple activities, the squares are split diagonally to show different categories. ated by a diagonal line. For multiple categories, I'll use parallel diagonal bands — equal-width offsets along the perpendicular direction. I'm considering making the band widths proportional to time spent rather than equal, which would make the visualization more informative and match the reference style better.
I'm thinking through the geometry: for a square divided by lines parallel to the main diagonal, I can use clipping to render each colored band as a rectangle clipped to a polygon region. I need to set up the coordinate system and define how the diagonal lines map across the space.
Now I'm working out the area formula for regions bounded by these parallel lines—for positive offsets it's a triangle with area (s-c)²/2, and for negative offsets it's s² - (s+c)²/2. This lets me compute the cumulative fractions needed to assign colors to each band.
To find the boundary lines between categories, I invert the area formula: if the cumulative area is at most half the square, I use c = s - sqrt(2A), otherwise c = sqrt(2(s²-A)) - s. Then I'll clip the square polygon against each pair of boundary lines using Sutherland–Hodgman to get the actual polygonal regions for each category.
For the visual ordering, I'm thinking about whether to place the largest category (most minutes) in the bottom-left to match the reference image where purple dominates that region.
On tooltips, native SVG <title> elements work fine if the SVG is embedded as an object or inlined, but they won't function inside an <img> tag. Since the goal is a self-contained image for a webpage, I'll need to either embed it with <object> or inline it directly, and I can add custom styling with a <style> block inside the SVG itself.
I'm thinking the best approach is to include both native <title> elements for accessibility and a fallback, plus optional JavaScript for a styled tooltip that shows a dark rounded box with gruvbox colors. If JavaScript is disabled or the SVG is embedded as an image, it gracefully degrades. The simplest solid deliverable would be a Python script that generates a standalone SVG file, possibly with an HTML demo wrapper to show how to use it.
I'm planning to create a Python script that parses the activity log and renders the SVG, include sample input data, and output the final SVG so it displays directly. I'll skip the separate demo file and just provide the SVG with inline instructions on how to embed it.
Now I'm working through the layout dimensions from the reference image—roughly 1570x768 pixels total, with about 90 pixels on the left for month labels...
Calculating the grid spacing...
Now I'm thinking through the parsing logic—I'll use a regex to extract the date, time, duration in minutes, category, and description from each line. Then I'll aggregate the data by date and category, tracking both the total minutes and individual entries. For the color scheme, I'll use a gruvbox material palette and either assign colors based on the order categories first appear or accept a custom color mapping via configuration. The legend will follow whichever ordering I use.
For the calendar layout, I'll render months in rows, filling in days with activity data or marking empty days as grey with "no activity." Days that fall outside the month (like February 29–31) won't be drawn at all. I'll add a year separator line before the first month of each new year, except at the very start. The tooltip will show the date, category, and total minutes, followed by a list of individual time entries and their descriptions. I'm planning to build a custom JavaScript tooltip with a styled rectangle and text for better presentation than the native browser tooltip, and I'll handle SVG text wrapping by pre-splitting lines manually.
I also want to check the frontend-design skill guide to make sure I'm following best practices for the UI. Then I'll write a Python script to generate the SVG calendar from a time-log file, create some sample data, run it, and present the result.
Writing the Python script... I'm mapping out the color palette using Gruvbox Material Dark colors for the seven legend categories, then setting up the background colors with the hard variant for the page background, a slightly lighter shade for empty cells, and muted text colors for contrast.
Now I'm working through the geometry calculations for the calendar grid — setting cell size to 40 pixels with a 6-pixel gap between them, which gives a 46-pixel pitch. The month labels sit in a left column at x=88, day numbers start at y=62, and I'm computing the total width by accounting for 31 columns of cells plus margins to reach around 1540 pixels wide. For the row spacing, I'm using a similar 46-pixel pitch to keep things consistent.
Below the calendar, I'm adding a year separator line and a legend with color swatches and labels. For the clipping logic, I'm implementing a half-plane clipping algorithm using the Sutherland-Hodgman approach to handle diagonal boundaries defined by the constraint x - y >= c or x - y <= c.
Implementing polygon clipping...
For the visual rendering, I need to handle rounded corners on the band cells. Since SVG polygons can't have rounded corners directly, I'm using a clipPath with a rounded rectangle and placing the band groups inside it with appropriate translations so the clipping applies correctly in user space.
For single-category days where there's only one band filling the entire cell, I'll draw a rounded rectangle directly for cleaner edges. Empty days still need handling too.
Now I'm setting up the JavaScript tooltip system. I'll store the tooltip text in a data-tip attribute on each shape, then create a hidden tooltip group with a rectangle and text element that gets positioned and shown on hover. The script will run on page load and attach event listeners to the SVG shapes to display the appropriate tip text.
For the hover highlight effect, I'm using a rounded rectangle overlay per cell with CSS to show a stroke outline on hover rather than changing the shape's stroke directly, which keeps the visual cleaner.
I'll use a font stack starting with Lato for that geometric sans-serif look, with fallbacks to system fonts. Now I'm ready to write the main script, generate sample data across roughly eleven months, and output the SVG file along with a CLI that accepts the log file, output path, and optional color and title parameters.
For ordering categories, I'll track them by first appearance in the log file and assign colors in that same sequence, but allow a JSON override via the --colors flag to customize both the mapping and the display order. I need to handle edge cases like year boundaries and days with multiple categories, plus format the tooltip text carefully—showing the date and category on the first line, total minutes and entry count on the second, then each individual entry with its time and description truncated to about sixty characters.
Writing the implementation now... Writing SVG code...
I'll check the design skill first, then build this.

7 # Frontend Design
8
9 Approach this as the design lead at a small studio known for giving every client a visual identity that could not be mistaken for anyone else's. This client has already rejected proposals that felt templated, and is paying for a distinctive point of view: make deliberate, opinionated choices about palette, typography, and layout that are specific to this brief, and take one real aesthetic risk you can justify.
10
11 ## Ground it in the subject
12
13 If the brief does not pin down what the product or subject is, pin it yourself before designing: name one concrete subject, its audience, and the page's single job, and state your choice. If there's any information in your memory about the human's preferences, context about what they're building, or designs you've made before – use that as a hint. The subject's own world, its materials, instruments, artifacts, and vernacular, is where distinctive choices come from. Build with the brief's real content and subject matter throughout.
14
15 ## Design principles
16
17 For web designs, the hero is a thesis. Open with the most characteristic thing in the subject's world, in whatever form makes sense for it: a headline, an image, an animation, a live demo, an interactive moment. Be deliberate with your choice: a big number with a small label, supporting stats, and a gradient accent is the template answer, only use if that's truly the best option.
18
19 Typography carries the personality of the page. Pair the display and body faces deliberately, not the same families you would reach for on any other project, and set a clear type scale with intentional weights, widths, and spacing. Make the type treatment itself a memorable part of the design, not a neutral delivery vehicle for the content.
20
21 Structure is information. Structural devices, numbering, eyebrows, dividers, labels, should encode something true about the content, not decorate it. Many generic designs use numbered markers (01 / 02 / 03), but that's only appropriate if the content actually is a sequence - like a real process or a typed timeline where order carries information the reader needs. Question if choices like numbered markers actually make sense before incorporating them.
22
23 Leverage motion deliberately. Think about where and if animation can serve the subject: a page-load sequence, a scroll-triggered reveal, hover micro-interactions, ambient atmosphere. An orchestrated moment usually lands harder than scattered effects; choose what the direction calls for. However, sometimes less is more, and extra animation contributes to the feeling that the design is AI-generated.
24
25 Match complexity to the vision. Maximalist directions need elaborate execution; minimal directions need precision in spacing, type, and detail. Elegance is executing the chosen vision well.
26
27 Consider written content carefully. Often a design brief may not contain real content, and it's up to you to come up with copy. Copy can make a design feel as templated as the design itself. See the below section on writing for more guidance.
28
29 ## Process: brainstorm, explore, plan, critique, build, critique again
30
31 For calibration: AI-generated design right now clusters around three looks: (1) a warm cream background (near #F4F1EA) with a high-contrast serif display and a terracotta or warm-clay accent (often near #D97757 — Anthropic's own Claude-interaction accent, so on a user's brief it reads as a tell); (2) a near-black background with a single bright acid-green or vermilion accent; (3) a broadsheet-style layout with hairline rules, zero border-radius, and dense newspaper-like columns. All three are legitimate for some briefs, but they are defaults rather than choices, and they appear regardless of subject. Where the brief pins down a visual direction, follow it exactly — the brief's own words always win, including when it asks for one of these looks. Where it leaves an axis free, don't spend that freedom on one of these defaults. Just like a human designer who's hired, there's often a careful balance between doing what you're good at and taking each project as a chance to experiment and learn.
32
33 Work in two passes. First, brainstorm a short design plan based on the human's design brief: create a compact token system with color, type, layout, and signature. Color: describe the palette as 4–6 named hex values. Type: the typefaces for 2+ roles (a characterful display face that's used with restraint, a complementary body face, and a utility face for captions or data if needed). Layout: a layout concept, using one-sentence prose descriptions and ASCII wireframes to ideate and compare. Signature: the single unique element this page will be remembered by that embodies the brief in an appropriate way.
34
35 Then review that plan against the brief before building: if any part of it reads like the generic default you would produce for any similar page (work through a similar prompt to see if you arrive somewhere similar) rather than a choice made for this specific brief — revise that part, say what you changed and why. Only after you've confirmed the relative uniqueness of your design plan should you start to write the code, following the revised plan exactly and deriving every color and type decision from it.
36
37 When writing the code, be careful of structuring your CSS selector specificities. It's easy to generate CSS classes that cancel each other out (especially with a type-based selector like .section and a element-based selector like .cta). This can happen often with paddings/margins between sections.
38
39 Try to do a lot of this planning and iteration in your thinking, and only show ideas to the user when you have higher confidence it'll delight them.
40
41 ## Restraint and self-critique
42
43 Spend your boldness in one place. Let the signature element be the one memorable thing, keep everything around it quiet and disciplined, and cut any decoration that does not serve the brief. Not taking a risk can be a risk itself! Build to a quality floor without announcing it: responsive down to mobile, visible keyboard focus, reduced motion respected. Critique your own work as you build, taking screenshots if your environment supports it – a picture is worth 1000 tokens. Consider Chanel's advice: before leaving the house, take a look in the mirror and remove one accessory. Human creators have memory and always try to do something new, so if you have a space to quickly jot down notes about what you've tried, it can help you in future passes.
44
45 ## More on writing in design
46
47 Words appear in a design for one reason: to make it easier to understand, and therefore easier to use. They are design material, not decoration. Bring the same intentionality to copy that you would bring to spacing and color. Before writing anything, ask what the design needs to say, and how it can best be said to help the person navigate the experience.
48
49 Write from the end user's side of the screen. Name things by what people control and recognize, never by how the system is built. A person manages notifications, not webhook config. Describe what something does in plain terms rather than selling it. Being specific is always better than being clever.
50
51 Use active voice as default. A control should say exactly what happens when it's used: "Save changes," not "Submit." An action keeps the same name through the whole flow, so the button that says "Publish" produces a toast that says "Published." The vocabulary of an interface is the signposting for someone navigating the product. Cohesion and consistency are how people learn their way around.
52
53 Treat failure and emptiness as moments for direction, not mood. Explain what went wrong and how to fix it, in the interface's voice rather than a person's. Errors don't apologize, and they are never vague about what happened. An empty screen is an invitation to act.
54
55 Keep the register conversational and tuned: plain verbs, sentence case, no filler, with tone matched to the brand and the audience. Let each element do exactly one job. A label labels, an example demonstrates, and nothing quietly does double duty.
56

I need to stick to the brief's specifications—matching the reference image and using the Gruvbox Material palette—then start writing the code.
The brief pins the visual direction tightly, so I'll match the reference layout and swap in Gruvbox Material.

I'm verifying the legend positioning—the last label ends around x=1306 and the legend is centered by design, so that checks out. Now I'll export the SVG to see how it renders.
Wait, I should make the script more robust. When the SVG is inlined in HTML, document.currentScript works during parsing, but if it's injected dynamically later, currentScript could be null. I'll add a fallback that queries for the SVG element if currentScript isn't available, and maybe use a random suffix for IDs to avoid conflicts if multiple calendars end up on the same page. Let me patch that quickly.

The SVG above is rendered from a synthetic 447-entry log covering Sep 2025 – Jul 2026, since you didn't attach your actual file. Point the script at yours:
Diagonal slices are proportional to time. In your reference the split looks fixed; here the area of each band equals that category's share of the day's minutes, with the largest slice in the bottom-left and the smallest in the top-right corner. Days with four or five categories degrade gracefully into thin stripes.
Colours are Gruvbox Material dark (medium contrast) — blue #7daea3, purple #d3869b, green #a9b665, red #ea6962, orange #e78a4e, yellow #d8a657, aqua #89b482, on #1d2021 with #32302f for no-activity cells and #d4be98 for text. Categories take colours in order of first appearance; pass --colors colors.json with a {"Restoration": "#d3869b", ...} mapping to pin specific ones and fix the legend order.
Tooltips work two ways: a native <title> per segment (always works, unstyled), plus a styled Gruvbox tooltip drawn in-SVG that follows the cursor and lists each entry's start time and description for that category on that day. The styled version needs scripting, so embed it inline or via <object data="calendar.svg" type="image/svg+xml"> — inside an <img> tag the browser blocks both scripts and hover, and you'd get a static picture.
The font stack is Lato first, falling back to system sans. Your reference looks like Lato or a close humanist cousin; if you're self-hosting a different face, change the FONT constant near the top of the script. Everything else lives in the geometry block just under it — CELL, COL_PITCH, ROW_PITCH, RADIUS.
Lines that don't match the expected format are skipped and reported on stderr rather than silently dropped, so a typo in the log doesn't quietly vanish from the chart.

The proportions covered by different categories are off. If there are X categories in a day, the diagonal width of each category should be the same (square diagonal/X); currently, it seems each category is assigned it's own layer and this is shown/hidden? When opening the SVG in a browser, two labels show. The custom label popup looks better. The label should only contain the duration and description. The cell highlight color seems out of place when hovering.

The key insight is that the bands need equal perpendicular distance along the diagonal direction, not proportional area. For X categories, I should divide the anti-diagonal (running from top-right to bottom-left) into X equal segments, since the band lines are parallel to the main diagonal.
For the labels, I'm removing the native <title> element in favor of the custom tooltip since it looks better, and dropping the aria-label for accessibility. The tooltip itself should be simplified to show only duration and description per entry—no date headers or times, just something like "45 min · Description" for each line if there are multiple entries in the same category.
For the cell highlight, the current cream-colored outline feels out of place, so I'm exploring subtler options like a thin outline in a dark neutral tone or a slight lift effect instead.
On hover, I'll add a white overlay at low opacity inside the clipped cell area with a slight scale effect—this brightens the cell while preserving its hue without introducing a foreign color. The highlight rect needs to move inside the clip group so the rounded corners apply properly.
Since equal widths mean area no longer encodes time, I'm reconsidering the segment ordering. I could keep them sorted by minutes descending so the largest category sits bottom-left like before, though with equal widths the visual weight no longer communicates duration.
Now I'm implementing the diagonal bands function that calculates the upper and lower bounds for each band across the grid, then updating the tooltip to format each line with duration and description separated by an em dash, using muted styling for the duration text.
Four targeted fixes. Equal diagonal widths first:

The 2-band case creates degenerate triangles with duplicate vertices, which is fine—I'll deduplicate consecutive points for cleaner output. For the 3-band case, the first band forms a corner triangle with vertices at 13.33,0 40,0 40,26.67, where the leg length of 26.67 equals 40 times 2/3, which checks out.
The band spacing works out: each step is 26.67 units, the diagonal width per band is 18.86 (matching the square diagonal divided by 3), and the c-coordinate progression 40 → 13.33 → -13.33 → -40 is correct. Now I'm cleaning up the code by removing the unused math import and keeping only what's needed.

Equal diagonal widths. The cuts are now spaced evenly along the square's other diagonal — step = 2·side/count in the offset parameter, which works out to exactly diagonal/count of width per band regardless of how many categories share the day. A two-way split is the clean corner-to-corner diagonal; a three-way gives a 26.67-unit corner triangle on a 40-unit cell, and so on. Nothing is layered or toggled — each band is a genuinely clipped polygon, so what you see is the real geometry.
One tooltip. The native <title> elements are gone entirely, leaving only the styled popup. The file no longer degrades to browser tooltips if scripts are blocked, which is the tradeoff for not having them fight each other.
Tooltip content is now just duration and description, one line per entry, with the duration set in muted #928374 and the description in #d4be98. A category with three entries on one day gets three lines; no date header, no category name, no start times. The times are still parsed and kept in the data structure, so they're there if you want them back later.
Highlight is a white overlay at 16% opacity inside the cell's clip path, rather than a cream outline. It brightens whatever colours are under it instead of introducing a colour that belongs to the text, and because it sits inside the clip it follows the rounded corners.

Lose the opacity change on hover; no effect is sufficient. The color scheme does not look appealing; perhaps a lighter palette does not suit this application. The position of the year makes it ambigious. Make it appear before the first visible month of the year.

I need to make three adjustments: first, remove the hover highlight effect entirely by dropping the associated rect element and its styling. Second, swap out the current Gruvbox Material palette—the medium-contrast variant is too muted and washed out for this design, so I'll switch to a harder, more saturated variant with better contrast instead. I'll add a --palette flag to let them switch between the material and original gruvbox sets, making the vivid original palette the default since the brighter saturated colors will have better contrast against the dark background. The empty cells at #32302f are fine as-is — they'll recede naturally with the more vibrant accents. Now I'm looking at the year label positioning, which in the reference appears differently relative to the month rule. aligned in the gutter, so it clearly heads the block beneath it. For the first year, I'll skip the rule since there's no preceding block to separate from, and just place the label in the left gutter at the top of that year's block. To avoid collision with the day-number headers, I'll add a YEAR_GAP before the first row to create space for the "2025" label, keeping the layout clean and consistent.
Now I'm structuring the vertical layout with the header at a fixed position, then iterating through each year-month pair to place labels and draw rules between year transitions. I'm setting up the loop to track when the year changes and conditionally add spacing and rule lines, with a reserved space for the year label and rule above each block.
I'm working through the positioning math to ensure the day numbers at the top don't collide with the year labels, and that there's appropriate spacing between the header and the first row of data. Setting up the layout constants and loop structure... The blue is a bit muted compared to the reference's darker teal, but that works fine. I'm settling on the foreground text color as a lighter, warmer tone for better contrast, with muted grays for secondary elements and specific colors for empty cells, backgrounds, and rules. I'll add a --palette flag to support both the original and material color schemes, then implement these changes.
Three changes — killing the hover effect, swapping to the vivid Gruvbox brights, and re-anchoring the year label.

Hover effect is gone entirely — the overlay rect and its CSS are removed, so the only thing that happens on hover is the tooltip appearing.
Palette. You're right that the Material set was working against this: those accents are low-chroma mid-tones, and at 40px with three-way diagonal splits they muddy into each other. The default is now the original Gruvbox brights — #fb4934 red, #fe8019 orange, #fabd2f yellow, #b8bb26 green, #8ec07c aqua, #83a598 blue, #d3869b purple — with warmer #ebdbb2 text and a slightly lighter #3c3836 for empty days so they read as "nothing here" rather than as another category. The Material version is still available via --palette material (second file above, for side-by-side).
Year label. It now sits above the first visible month of every year, including the first one, right-aligned in the same gutter as the month abbreviations so it reads as a heading for the block beneath it. Previously only 2026 was labelled and it sat above its rule, which left it hovering ambiguously between the two blocks. The rule still only appears between years, since there's nothing to separate at the top of the grid.

I'm sketching out a dark color palette with blues and pinks—moving away from Gruvbox toward something more muted and moody on a near-black background. I'm organizing seven categories across two families, starting with a deep navy-to-slate blue ramp and planning the corresponding pink tones.
The challenge is making all seven swatches mutually distinguishable while keeping them dark. I'm spreading them across hue (210° to 340°) and lightness (around 20% to 55%) so each color has a unique position in that space, which gives the best separation under these constraints. Now I'm working through the exact HSL values to ensure adjacent colors are visually distinct without getting too bright. or go with 3 blues and 4 pinks instead. I'm settling on a palette with midnight blue, deep steel, and a medium slate blue, then transitioning through wine and mulberry tones into lighter pinks, keeping everything in the dark range as requested.
Now I'm deciding how to order these colors in the legend—alternating blue and pink for contrast, or arranging them as a smooth gradient from cool to warm, which would feel more intentional and cohesive visually. end is a key, not a gradient. The legend alternating between blue and pink actually reads as calm since there are only two hues, which works well for what they're asking for. For the palette, I'm using a near-black background like #16181c, cool dark grey for empty cells, and cool light grey text to match the blue-pink scheme rather than warm tones. The muted colors and rule lines stay subtle, and while the diagonal splits add visual complexity, I can't reduce the accent colors since there are seven categories to represent.
I'm creating a new "duotone" palette as the default while keeping the original and material options available. I'll darken the empty cells slightly to #23262b so the grid recedes more. For the color values, I'm picking blues that step clearly in lightness—midnight blue, steel, and a brighter steel—and plums that progress from dark to dusty rose, all with distinct enough contrast. Once I verify the distinguishability between the blues and the plum range, I'll implement this duotone palette as the default and update the legend accordingly.

Seven categories across two hues means separation has to come from lightness, so each family is a value ramp rather than a set of distinct colours. The assignment order alternates blue, pink, blue, pink — a legend that ran blue-to-pink as a smooth gradient would look tidier in isolation, but it would put adjacent categories at nearly identical values, and those are exactly the pairs most likely to share a cell diagonal.
Supporting colours went cool to match: near-black #16181c ground, #23262b for empty days, and #c9ced6 text instead of the warm cream, which was fighting the blues.
The earlier palettes are still there — --palette original or --palette material — and --colors colors.json still overrides individual categories if a particular one wants to sit at a specific value.

Everything looks great. Move the year to be in the same line as the first month. Do not change any other styling, positions or properties.

Looking at the user's modified visualization, they've scaled the circles by time logged per day with a single color scheme and a different layout than my original script. They want the year moved to the same line as the first month label instead of appearing on its own line above. Adjusting the year label positioning...
The month labels are right-aligned around x=72 in my layout, so placing the year to the left would require significant horizontal space—the year "2025" would start near x=0, which is too cramped. Their image shows a wider gutter with more breathing room, but they've asked me not to change other styling. Since their version likely has different dimensions anyway, I should focus on just moving the year inline with the first month row in my current script, keeping the constraint that I can't alter other properties. There's only an 8px gap between where the year label ends and the month labels begin, which is tight but manageable. The rule starts at x=42, slightly left of where the year would sit, which mirrors their layout where the rule spans the full width above the year label. I'll keep the current positioning and place the year label accordingly. Jan row top D+76 → 22 above, 14 below. But the constraint says not to change other properties, yet I need visual balance. Let me try splitting the gap evenly: after Dec, add 14 to position the rule at D+62 (22 pixels below the Dec cells), then add another 14 to place the Jan row at D+76, giving 14 pixels of breathing room below the rule. Writing spacing logic... The year label positioning is creating a collision with the month labels. If I right-align "2025" at x=36 or x=38, it's too close to the edge. Left-aligning it at x=8 puts it only 1 pixel away from where "Sep" starts at x=44, which is too tight. I need to increase the LEFT margin to create proper breathing room between the year and month labels. Let me work through the math: with the current LEFT=88, I have about 72px of usable space for labels. The year at 14px with letter-spacing takes roughly 35px, the month about 28px, plus a 10px gap and 12px padding — that's 85px total, which overshoots by about 13px. I could shrink the year font to 13px without letter-spacing to save space, but that changes the styling. The cleaner approach is probably to just widen LEFT. I'm debating whether to keep the rule's x-position tied to the LEFT variable or set it to a fixed margin value. With LEFT at 128, the rule would start at 82, which sits right of the year label—visually acceptable since it separates the grid area. Their reference image has the rule starting further left at 24, but that's a different design choice. I'll stick with the LEFT - 46 relationship to minimize changes and keep the proportional spacing intact.
Now I'm ready to implement the layout with LEFT = 128 and GRID_TOP = 64, removing the separate year and separator constants and instead using the rule gap logic. The year label will align with the first month row at a right-aligned position of LEFT - 56, and the vertical spacing will start from GRID_TOP.

The year now shares a baseline with its first month — 2025 with Sep, 2026 with Jan — sitting to the left of the month abbreviation in the gutter.
Two knock-on changes were unavoidable, both forced by the move itself:
The gutter had to widen from 88 to 128 to fit two labels side by side. At the old width the year would have started at roughly x = −1, running off the canvas. The month labels keep their right-aligned position relative to the grid; the year right-aligns 40px further left, and the canvas grows to 1580 wide.
The dedicated year line collapsed, so rows above and below a year boundary moved up. The rule between years stays, now with 10px above and 18px below it rather than a full label row. Everything else — cell size, pitch, radius, colours, fonts, legend, tooltip — is untouched.
