Fixes#568. Adds a real --color-ring token (ink orange #A85518 light / #F0A766 dark) and sweeps all 57 focus-indicator occurrences onto it: soft opacity rings blended to 1.2-1.7:1, border-only indicators sat at 2.6-3.0:1, and four focus:ring-ring sites referenced a token that never existed. Sponsor button keeps pink via pink-700; range sliders and the file list gain their missing keyboard indicators; landing skip link and form borders hardened; the palette contrast guard pins the ring at 3:1 in both themes.
Fixes#557. Vivid fill, ink label: brand #E07832 stays on fills while primary-foreground flips to #1A1814 (5.83:1); new theme-aware ink tokens carry orange, destructive, and success text roles; opacity-modified text purged; landing, demo, and the docs fund button retuned. Guarded by a CSS-parsing unit contrast test, rebuilt axe baselines with zero contrast entries, a new landing axe smoke, and fully regenerated darwin visual baselines.
