/* ============================================================================
   Glass.
   html[data-season="glass"] — set before paint from wh-dark-mode-init.php.
   Off unless the Glass switch is on.

   The rail, account menu, and footer card are frost over a dark wash
   with a few soft color pools: amber up top, green through the middle,
   blue at the foot. The content card, tables, and ad grid stay opaque.
   Upgrade stays a solid fill. The accent stays the brand blue so this
   is a material, not a recolor.
