From f0addfdabf3dbeb2121dd954e03362bf4ebe7cd1 Mon Sep 17 00:00:00 2001 From: Kpa-clawbot Date: Thu, 11 Jun 2026 22:25:44 -0700 Subject: [PATCH] fix(#1668): palette indirection + WCAG AA token bumps (M2 + #1671) (#1676) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Red commit: d761516d6009bbab9dbab71f80c70f67b28fcb35 (no CI run — branch-only push does not trigger workflows on this repo; verified locally: `node test-issue-1668-m2-contrast.js` fails on assertion at HEAD~1, passes at HEAD) Partial fix for #1668 (M2 of 6). Fixes #1671. ## What changed **Two-tier CSS tokens** introduced in `public/style.css`: 1. **Tier-1 (`--palette-*`)** — 38 raw colour stops, theme-independent, in a single `:root` block at the top of the file. Source: Tailwind v3 default palette (MIT, battle-tested for WCAG-graded luminance steps). - gray ×9, blue ×9, green ×5, amber ×5, red ×5, purple ×5 - Single source of truth: no rule outside this block uses raw `#hex`/`rgb()`. 2. **Tier-2 (semantic)** — existing `--text`, `--text-muted`, `--surface-*`, etc. re-plumbed to point at palette stops in both theme blocks. Behaviour preserved where contrast was already AA. **WCAG AA bumps for M1 BLOCKER tokens**: | Token / surface | Before | After | Theme | |---|---:|---:|---| | `--text-on-accent` on `--accent-strong` (was `#fff` on `--accent`) | 2.75:1 | **4.95:1** | dark + light | | `--text-muted` on `--surface-1` | ~3.5:1 | **11.58:1** | dark | | `--text-muted` on `--card-bg` | ~5.0:1 | **10.28:1** | dark | | `--text-muted` on `#ffffff` | 5.74:1 | **10.31:1** | light | | `--text-muted` on `--surface-0` | 5.32:1 | **9.45:1** | light | **New tokens**: `--accent-strong` (= `--palette-blue-600` = `#2563eb`), `--text-on-accent` (= `--palette-gray-50` = `#f9fafb`), `--text-subtle`. Rules migrated to the new accent pair (all were `#fff` on `var(--accent)` = 2.75:1 in the M1 audit): `.skip-link`, `.tab-btn.active`, `.filter-bar .btn.active`, `.filter-group .btn.active`, `[data-theme="dark"] .filter-bar .btn.active`, `.path-hops .hop-named`. ## Operator-reported chip (2026-06-12 — `.hop-named.hop-link`) Dark-blue text on dark-blue chip background. Patched via `.path-hops .hop-named` + `--accent-strong`. Now reads as `#f9fafb` on `#2563eb` = 4.95:1 (AA pass) in both themes. Before/after screenshots: see `a11y-audit/m2-screenshots/{before,after}-packets-{dark,light}-1200x900.jpg`. Letsmesh's UI uses chip text at 6.77:1 on equivalent surfaces; this PR closes most of the gap. ## TDD trail - Red commit `d761516d` — assertion-based contrast test, fails on missing palette. - Green commit `e5e87309` — palette + remap + bumps + AA pass. - Anti-tautology: reverting dark `--text-muted` back to `#6b7280` reproduces `text-muted on surface (dark): contrast 3.53:1 < 4.5:1`. ## Preflight `bash ~/.openclaw/skills/pr-preflight/scripts/run-all.sh origin/master` → all gates pass (incl. CSS-var-defined: 1928 var() refs, 0 undefined). ## Not in this PR (intentional) - M3 typography (`14px` floor + weight 500 for chips/badges) — own PR - M4-M5 per-route polish — own PRs - M6 axe CI gate — own PR - Shipping an alternate palette — deferred, indirection enables it --------- Co-authored-by: openclaw-bot --- public/style.css | 106 +++++++++++++++++++-- test-issue-1668-m2-contrast.js | 166 +++++++++++++++++++++++++++++++++ 2 files changed, 263 insertions(+), 9 deletions(-) create mode 100644 test-issue-1668-m2-contrast.js diff --git a/public/style.css b/public/style.css index 2ae14257..7b6bfe71 100644 --- a/public/style.css +++ b/public/style.css @@ -96,6 +96,67 @@ * further below — DO NOT add component CSS in this region. * ============================================================ */ +/* ============================================================ + * TIER-1 PALETTE — raw colour stops.
