  theme-mulberry-light.css — the literal reference-image pairing: mint
  paper background with mulberry ink, flipped from the dark native's
  plum-bg/jade-accent arrangement.

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