/* ============================================================================
   tokens.css — Terminal 5 design tokens (single source of truth)
   Loaded before style.css / index.html / admin.html inline styles.
   Light values live in :root; dark values override via
   @media (prefers-color-scheme: dark), matching the app's existing convention.

   Stage S2a: style.css consumes these --t5-* tokens directly. The
   Stage-S1 legacy alias block (old style.css :root names pinned to their
   pre-redesign values) has been removed now that style.css no longer
   references any of those names.
