V5 UI foundation: tokens, focus, motion, layering (Issue #763)

2026-04-01

  • Added `--z-*` z-index token system (10 named layers) to replace ad-hoc numeric stacking values.
  • Added global `:focus-visible` baseline so interactive controls show a visible keyboard-focus ring without affecting pointer interaction.
  • Added global `prefers-reduced-motion` baseline that collapses all animation and transition durations for users who opt in.
  • Added `.v5` migration wrapper class (`isolation: isolate`) as a stacking-context anchor for incrementally migrated routes.
