Review Change Stack

📝 Walkthrough

Walkthrough

The change adds four CWN themes with categorical color palettes, preserves those palettes during theme resolution, applies them to donut charts, and updates preview generation and README theme links.

Changes

CWN theme palettes

Layer / File(s) Summary
Theme contracts and CWN registrations
src/const/theme.ts, tests/const/theme.test.ts
Theme accepts categorical palettes. Four CWN themes define dark and light palettes with bordered and borderless variants. Theme resolution preserves the palette.
Donut categorical-color rendering
src/templates/donut-chart-card.ts, tests/templates/donut-chart-card.test.ts
Donut legends and arcs use indexed theme colors, with datum colors as fallback. SVG tests cover both paths.
Theme showcase and documentation
scripts/generate-preview-assets.ts, README.md
Preview generation includes the four CWN themes and uses cwn_dark_border for hero assets. The README links to their previews.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 3c996

Larger CWN donut and language cards can lose their monochrome styling after five items because later entries use fallback colors, so the PR is not merge-ready until that behavior is corrected. The theme preview images also need descriptive alt text for accessibility.

Add alternate text to the theme previews.

On Line 53, all five Markdown images use empty alternate text. Add concise descriptions so screen readers can identify each preview and the MD045 warning is resolved.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Cycle the categorical palette when the donut has more items than palette entries.

CWN_DARK_CATEGORICAL_COLORS and CWN_LIGHT_CATEGORICAL_COLORS have five entries. data has no five-item limit. Item six and later fall back to d.data.color, so CWN language cards no longer use monochrome colors.

Use the palette index modulo its length in both locations. Add a test with more items than the palette length.

Proposed fix
+    const getCategoricalColor = (datum: {data: {color: string}}, index: number) => {
+        const colors = theme.categoricalColors;
+        return colors?.length ? colors[index % colors.length] : datum.data.color;
+    };
+
-        .attr('fill', (d, i) => theme.categoricalColors?.[i] ?? d.data.color)
+        .attr('fill', getCategoricalColor)
...
-        .style('fill', (d, i) => theme.categoricalColors?.[i] ?? d.data.color)
+        .style('fill', getCategoricalColor)
