Paul BakausandClaude Opus 4.6 8b93dfad5e Merge color/motion/glow/layout fixture pairs into side-by-side files
Each problem-space fixture is now a single file with two columns: left
for cases that should flag, right for cases that should not. Matches the
icon-tile-stack convention and makes browser-based visual review easier.
The pass column proves that no false positives leak from look-alike
patterns next to the real anti-patterns.

Merged (4 pairs → 4 files)
- color-should-{flag,pass}.html → color.html
- motion-should-{flag,pass}.html → motion.html
- glow-should-{flag,pass}.html → glow.html
- layout-should-{flag,pass}.html → layout.html

Left untouched
- should-{flag,pass}.html — used by the CLI smoke tests in
  detect-antipatterns.test.js, which need a known-clean fixture for the
  exit-code-0 path.
- typography-should-{flag,pass}.html — all three typography rules
  (overused-font, single-font, flat-type-hierarchy) are page-level and
  fundamentally can't share a page with their pass cases. Loading two
  font stacks suppresses single-font; varied sizes suppress flat-type-
  hierarchy. Documented in the test file.

Test calibration
- Hardcoded the jsdom finding counts (motion: 2 bounce + 2 layout-
  transition; glow: 1 dark-glow). Real browser sees more because
  jsdom doesn't fully apply class-based styles, but the pass-column
  count is reliably 0. Browser-verified all 4 fixtures show expected
  flag counts and zero pass-column false positives.

Fixture chrome fixes
- Sub-section labels (.col h3) now use #64748b instead of #94a3b8 so
  the fixture's own UI doesn't trigger low-contrast. glow.html got a
  CSS restructure into card-dark/card-light/card-medium variants so
  every text/background pairing meets WCAG AA. layout.html's "card
  with image" gradient changed from blue→purple to amber→rose so it
  doesn't trip ai-color-palette.
