/*
  theme-ember-light.css — warm paper background with deep midnight ink
  and a deepened ember accent (brightened orange fails AA on light
  paper, so this variant darkens it slightly rather than reusing the
  native hex verbatim).

  Scoped under `body[data-theme="ember"].theme-light` (compound
  selector, beats theme-ember.css's single-attribute rules on
  specificity). Toggled at runtime by js/color_scheme.js. Radius/font
  stay the same as the native file — only surfaces/text/accent flip.
