/* =========================================================
   v2 LIGHT EDITORIAL MIGRATION
   ---------------------------------------------------------
   Page was authored as a dark glass theme (--ss-ink near-white,
   surfaces built from translucent white meant for a dark page).
   The shared shell is now light (body #fff), so cards went
   white-on-white and near-white text vanished. Remap the page's
   local text/line/accent/shadow tokens to the light system and
   give every translucent surface a solid light background.
   Intentionally-dark code boxes keep their own light code text.
