/* theme.css - canonical component styling for the Directory Factory.
   Ships byte-identical in BOTH the Engine A and Engine B starters. Both engines emit
   the same canonical class names, so this one stylesheet themes both identically and a
   palette/theme swap (tokens only) reskins both. Uses ONLY var(--token); no literal
   colors. Canonical classes:
