   There is intentionally NO @media (prefers-color-scheme: dark) rule, so the

   explicitly opts in. A toggle can be wired later (out of scope here).

   This redefines only the surface / text / border tokens (page chrome:
   backgrounds, nav, footer, cards, borders, body text). Accent greens, golds
   and blues are kept as-is so they stay readable on dark surfaces.

   NOTE: this is a foundation, not a complete dark skin. Some cards/badges use
   hardcoded rgba(...) accent backgrounds applied inline in the .razor pages
   (e.g. rgba(74,144,217,0.12), rgba(244,162,97,0.15)); those tints won't fully
