/* ---- Aquila Path brand tokens (see aquila-path-brand-system.html) ----
   Original semantic names kept (--eosin, --teal, --amber, --yellow) so every
   existing rule below still works -- only what they point to changed:
   --eosin (primary accent) -> purple, --amber/--yellow (wrong-class / boundary
   flag) -> rose. --teal (the "this tile is correct" action) stays its own
   green by explicit request, rather than folding into purple/rose. */
