fix(theme): normalize preset palettes for WCAG contrast, layering, radius - #336
Merged

Conversation
…dius Audited all 11 non-default presets across light/dark with a computed WCAG pass (contrast from the generated HSL triplets, no eyeballing): 62 findings — dim secondary text, white-on-midtone fills, near-invisible focus rings, and canvas/card pairs rendered at identical lightness. Generator (scripts/generate-theme-presets.mjs): - normalizeMode() now runs on every preset mode: canvas separates from card by >= 0.015 relative luminance (hue preserved), text-on-fill pairs clear 4.5:1 (search moves the fill, capped, then flips the text color), muted-foreground clears 4.5:1 against canvas and card, and the focus ring clears 3:1. Rerunning gen:themes reproduces the fixes. Runtime: - Hardcoded 6px/8px radii in the shell classes now derive from --radius (var(--ui-radius-sm/md)), so 1rem/1.4rem presets get coherent corner rounding on inputs, buttons, chips, menus and cards instead of 6px controls next to 22px cards - Preset elevation is tiered again: subtle/elevated/dialog derive from the preset shadow color with rising opacity instead of sharing one flat recipe - Default theme destructive moved to red-600 (white text measured 3.76:1 on red-500); mirrored in the default preset palette Verified: computed audit re-run on the generated file reports 0 remaining contrast/layering findings; rendered walkthrough of claude, whatsapp, enterprise-mod-2 (1.4rem radius) and t3-chat in both modes confirms the presets keep their identity. lint/typecheck/vitest (797) green.

In `@scripts/generate-theme-presets.mjs`:
- Around line 278-279: Update the contrast validation around the
muted-foreground check to include out.muted alongside out.background and
out.card in the surfaces collection, then regenerate the theme presets so all
generated values reflect the updated validation.
- Line 280: Update the ring generation around ensureTextOnSurfaces so the focus
indicator used by textarea:focus, input:focus, and select:focus renders as an
opaque hsl(var(--ring)) value and achieves at least 3:1 contrast; do not rely on
the separate :focus-visible outline to compensate for the translucent
--ui-accent-ring shadow.

Summary
All 11 non-default theme presets are audited and normalized with the same treatment the default theme received in #334. Every change is derived from a computed WCAG audit (contrast from the generated HSL triplets), not visual guessing. No business logic changes.
Audit method
A script evaluates every preset × mode for the pairs the shared components actually render: body/card text, dim text, primary/secondary/accent/destructive fills with their foregrounds, popover text, and focus ring vs canvas (4.5:1 text / 3:0 UI thresholds), plus canvas/card surface separation.
Baseline: 62 findings across the presets — dim secondary text (claude 3.65:1), white text on midtone fills (destructive pairs 2.85–3.92:1 in 10 modes, primary in 4), focus rings below 3:1 (light-green 1.30:1), and 13 canvas/card pairs at identical lightness (flat surfaces).
