/* ==========================================================================
   SVPPL — light-base industrial system with a dark cinematic hero
   Poppins / Inter / JetBrains Mono · Rich motion (GSAP/Lenis)

   THEME MODEL
   -----------
   Light is the DEFAULT (`:root`); dark is opt-in via `html[data-theme="dark"]`.
   Every section, card and component is authored against the ink/text tokens
   below, so re-pointing those tokens repaints the whole site from one place.

   The hero is deliberately dark in BOTH themes — see `.surface-dark`, which
   pins its own local token scope rather than inheriting the page theme.

   See BUILD-BRIEF.md §7. The reference site's toggle was broken (it flipped
   its own icon but never set the class); this one actually works and persists.

     `--accent` is the vivid safety orange used for fills, icons and large

     wherever text sits ON the orange, or orange text sits on a light surface.

     3:1 white-on-orange contrast failure the reference has. */
