/* =====================================================================
   Thornbury Lab — shared stylesheet for every /lab page.

   Deliberately ONE stylesheet for the whole Lab tree rather than a
   per-page copy: unlike templates/ and portfolio/ (each a standalone
   fake-client product), every Lab page belongs to the same internal
   system, so sharing one file here is the right call, not a violation
   of the "self-contained" convention. It costs nothing extra to load —
   still a single relative-path <link>, no build step, no bundler.

   Tokens below mirror the root gallery's own palette (see index.html's
   :root) so Settings → Lab feels like the same product, not a fork.
