   ----------------------------------------------------------------------------
   Immersion overlay for sacred-chemistry.html. Loaded AFTER:
     - ancient-medicine.css   (functional layout for the wheel)
     - liquid-glass.css       (glass primitives)
     - themes.css             (role color tokens)

   This file does not redefine layout. It adds the contemplative artifact
   surface: cosmos backdrop, phi-pulse animations, scrying tooltip, sound
   pill, portal dialog, citation tray, crescendo overlay, ritual close.

   Token reference (set on :root in the HTML):
