/*
  theme-noir-light.css — pale lavender-white paper with near-black ink,
  flipped from the dark native's near-black-bg/mauve-accent
  arrangement. Mauve deepened for contrast against the light paper;
  the literal Prestige Mauve hex becomes --accent-soft here.

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