From f4f5f8aa034a7da5ad6f1cc14dca2e63e7f1f848 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 6 Jun 2026 22:21:27 +0000 Subject: [PATCH 1/5] feat: add Tier-1 sRGB color fallbacks for pre-Chrome-123 / pre-Safari-17.5 engines MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the "gate at declaration site" pattern to fix IACVT failures on engines lacking light-dark(), oklch(from…), @property, or color-mix() support. Architecture: - core/tokens.color-fallbacks.css: generated sRGB defaults in @layer slashed.tokens (light) and @layer slashed.themes (dark), loaded before core/tokens.css in all 10 bundles - core/tokens.css: all light-dark() / oklch(from…) / color-mix() declarations wrapped in @supports blocks, making sRGB defaults the Old_Engine fallbacks - scripts/gen-color-fallbacks.js: build-time generator using culori for perceptually accurate OKLCH→sRGB conversion with full formula replay - scripts/verify-color-tokens.js: validates source token inventory Test suite (P1–P11 + fast-check, 195 unit tests + 376 Playwright): - P1: sRGB validity; P2: coverage/uniqueness; P3: source ordering - P4: @property mirror drift; P5: gamut mapping; P6: idempotence - P7: Old_Engine cascade simulation; P8: Modern_Engine baseline - P9: perceptual ΔE_OK ≤ 0.12; P10: WCAG 2.1 AA contrast - P11: override propagation (old vs modern engine) https://claude.ai/code/session_01QqME6SfLKZZkJD2W8Tgb3P ---

charset=UTF-8 Content-Transfer-Encoding: 8bit Eliminates the build-time generator in favour of CSS hsl() + calc() expressions that recompute automatically when users override brand channel variables, with no build step required on any browser from Chrome 49+. Changes: - core/tokens.color-fallbacks.css: 343-line generated file → 80-line static file using --sf-*-h/s/l channel variables + hsl(var() calc()) derivations - Removes scripts/gen-color-fallbacks.js and scripts/verify-color-tokens.js - Removes gen:fallbacks script from build; build is now just node scripts/bundle.js - Removes CI drift-check step (no generated file to drift) - Dark mode fallbacks removed — handled exclusively by modern CSS (@supports gates) - Drops 5 tests tied to the generator (P4/P5/P6/P9/idempotence/verify) - Updates P1/P3/P7/P10/P11 for the new HSL-based architecture To apply a brand colour on any browser: :root { --sf-primary-h: 340; --sf-primary-s: 80%; --sf-primary-l: 50%; } https://claude.ai/code/session_01QqME6SfLKZZkJD2W8Tgb3P --- .github/workflows/ci.yml | 1 - core/tokens.color-fallbacks.css | 381 +++------------- package.json | 5 +- scripts/artifacts.json | 3 +- scripts/gen-color-fallbacks.js | 655 --------------------------- scripts/verify-color-tokens.js | 177 -------- tests/accepted-degradation.json | 1 - tests/fixtures/tokens-corrupt.css | 1 - tests/fixtures/tokens-mismatch.css | 9 - tests/fixtures/tokens-missing.css | 10 - tests/gen-color-fallbacks.test.js | 200 -------- tests/tier1-p1-srgb-validity.test.js | 61 +-- tests/tier1-p10-contrast.test.js | 126 +++--- tests/tier1-p11-overrides.test.js | 148 +++--- tests/tier1-p3-ordering.test.js | 2 +- tests/tier1-p4-drift.test.js | 103 ----- tests/tier1-p5-gamut.test.js | 122 ----- tests/tier1-p6-idempotence.test.js | 68 --- tests/tier1-p7-oldengine.test.js | 5 +- tests/tier1-p9-perceptual.test.js | 135 ------ tests/verify-color-tokens.test.js | 138 ------ 21 files changed, 225 insertions(+), 2126 deletions(-) delete mode 100644 scripts/gen-color-fallbacks.js delete mode 100644 scripts/verify-color-tokens.js delete mode 100644 tests/accepted-degradation.json delete mode 100644 tests/fixtures/tokens-corrupt.css delete mode 100644 tests/fixtures/tokens-mismatch.css delete mode 100644 tests/fixtures/tokens-missing.css delete mode 100644 tests/gen-color-fallbacks.test.js delete mode 100644 tests/tier1-p4-drift.test.js delete mode 100644 tests/tier1-p5-gamut.test.js delete mode 100644 tests/tier1-p6-idempotence.test.js delete mode 100644 tests/tier1-p9-perceptual.test.js delete mode 100644 tests/verify-color-tokens.test.js diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index d656144e..11c1180d 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -54,7 +54,6 @@ jobs: - run: npm ci - run: npm run audit:check - run: node scripts/check-artifacts.js --check - - run: node scripts/gen-color-fallbacks.js && git diff --exit-code core/tokens.color-fallbacks.css test: name: Regression tests diff --git a/core/tokens.color-fallbacks.css b/core/tokens.color-fallbacks.css index 3719ddd2..55c88f19 100644 --- a/core/tokens.color-fallbacks.css +++ b/core/tokens.color-fallbacks.css @@ -1,343 +1,86 @@ -/* SLASHED — core/tokens.color-fallbacks.css (@layer slashed.tokens + slashed.themes) - GENERATED FROM SOURCE by scripts/gen-color-fallbacks.js - Regenerate: npm run gen:fallbacks - Do NOT edit by hand — changes will be overwritten. */ +/* SLASHED — core/tokens.color-fallbacks.css (@layer slashed.tokens) + HSL-based fallbacks for browsers without light-dark() / oklch(from…) support. + Light mode only — dark mode is handled by modern CSS exclusively. + Customise by overriding the --sf-*-h / --sf-*-s / --sf-*-l channel variables;
