   v6 — dark glass (loaded last).
   Near-black canvas with a soft glow in the theme colour, round glass
   buttons, pill-shaped cards with gradient icon badges, monospaced marks,
   a floating capsule tab bar and floating sheets.

   Theme = data-mode (dark | light) × data-accent (default | mono | tide |
   olive | ember | blossom), both set by js/theme.js. Every rule is scoped to
   html[data-mode] so it outranks the older layers without !important.
