/* ============================================================
   ANIMA ADVENTURES — DESIGN SYSTEM
   ------------------------------------------------------------
   Structure replaces decoration. Typography carries hierarchy.
   Deliberate emptiness gives the reader room.

   RULES FOR ANY FUTURE EDIT
   1. No component rule may contain a hex or rgba() value.
      If you are typing a colour outside the token blocks,
      a token is missing. Add it there instead.
   2. Content starts at column 1 or column 7. Nowhere else.
      Position is declared once, on the section, via data-col.
   3. Separation is a 1px hairline. Never a box, card, shadow,
      radius or gradient.
   4. Accent colours appear only as a 2px keyline marking a
      journey type. Never a background, block or button.
   5. The page background crossfade is the only scroll effect.
      Sections themselves never animate.
   6. Nothing below 12px.

   CANONICAL NAV BLOCK — keep byte-identical across all pages
   so one find/replace maintains it. Subpages use ../ prefixes.
