/* ── TagAudit "Improved UX" design layer (D291, R1) ────────────────────────────────────────────
   Corbel, 2026-10-01. Spec: Designs/Re-design 011026/design_handoff_tagaudit_improved_ux/README.md.
   Shared by every public page that adopts the redesign. Loaded AFTER base.css, so base's spacing
   scale, [hidden] guard and 12px legibility floor still apply.

   Rules carried from the handoff, not taste:
     · fonts are SELF-HOSTED (web/fonts/geist-*.woff2, OFL, see GEIST-OFL.txt) — no request to any
       third party before consent (RD-419's pre-consent gate);
     · hex is shipped (oklch optional per the README);
     · every animation and transition below is switched off under prefers-reduced-motion.
   The report family (report_template.html, demo_*_report.html) does NOT link this file: a report is
   saved and shared, so it stays self-contained (base.css's rule). The report is R2.
