   UraniumX theme tokens.

   Before 2026-08-27 the site carried 971 hardcoded colour literals across
   ten files, almost all inline styles assuming a black ground, in two
   competing ink systems (pure white and a warm off-white). Changing theme
   meant editing every one. These tokens make it one edit.

   Roles, not colours. --ink means "primary text on the current ground",
   which is near-white on a dark section and near-black on a light one.
   Never reintroduce a literal; add a role.

   The page ground is soft warm off-white; the hero, photo cards, nav and
   footer are dark islands marked .on-dark. Flipping the whole site between
   light and dark is now the :root block below and nothing else.
