/* ── Theme tokens: light is default, [data-theme="dark"] overrides ──────────
   Light theme contrast strengthened to WCAG AA across the board:
   - Page bg uses cool tinted gray (not white) so white cards stand out.
   - Borders pushed from 0.14 → 0.22 alpha so they are clearly visible.
   - Shadows layered (close + far) to create perceptible elevation.
   - Muted text 0.62 → 0.72, faint 0.42 → 0.58 to meet 4.5:1 on white. */
