Adds caption-side and empty-cells CSS properties with full parse→compute→inherit→layout pipeline. Fixes border-collapse hidden priority bug (§17.6.2.1 Rule 1: hidden wins unconditionally), empty-cell detection for whitespace-only anonymous children, and adds property-specific parsers rejecting invalid values. Includes 4 golden tests, 13 new unit tests, and checklist update. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
