  theme-bloom-dark.css — dark mode for the Bloom theme: deep plum-
  berry background instead of near-black, brighter pink for contrast,
  soft pink glow instead of a hard shadow.

  Scoped under `body[data-theme="bloom"].theme-dark` (compound
  selector, always beats theme-bloom.css's single-attribute rules on
  specificity). Toggled at runtime by js/color_scheme.js.
