/* ==========================================================================
   ATHERION - VISUAL SYSTEM
   Cinematic, full-bleed, scroll-driven. Replaces the previous concept sheet.

   Laws of the system
     1. Stages are full-bleed and full-viewport. Media goes edge to edge.
     2. Type overlaps media. It does not sit politely beside it.
     3. Corner radius comes from one scale (--r-sm/md/lg) and nothing else.
     4. No cards, no boxes. Rules, rails, crops and grounds instead.
     5. Blue is a ground/line/fill on dark; a text colour only on light.
     6. Every scroll-linked transform reads from --p, written by the engine.
