/* ─── Base ───────────────────────────────────────────────────────────────────── */
/* Background is two soft color glows painted directly as part of body's own
   `background` property — deliberately NOT pseudo-elements this time. A
   pseudo-element's visibility depends on z-index/stacking-context rules that
   went wrong twice in a row here; a plain background layer has no such
   failure mode; it is always painted, always behind body's children, no
   stacking context required. background-attachment:fixed keeps it visible
   while scrolling on long pages — the earlier concern about `fixed` was
   about a large bitmap photo specifically, not a cheap computed gradient
   like this one, so that tradeoff doesn't apply here.

   Light theme only, the two glows also slowly drift (bgDrift below) so the
   page doesn't sit dead still — the photo and flat tint layers stay put
   (animating those too would look janky on a full-viewport fixed image, and
   nobody's eye is on the corners anyway). That's why this is split into
   separate background-image/-position/-size properties instead of the
   single `background` shorthand: a shorthand bakes each layer's position
   into its own radial-gradient()/url() term, which isn't animatable, but
   background-position accepts one value per layer and can be keyframed. */

/* ── TomSelect dropdown theme ──────────────────────────────────────────────
   Every page using TomSelect (via the CDN <link>/<script> pair) needs this
   to match the app's own inputs instead of the library's bare default look.
   All theme-var-driven, so light/dark adapt automatically — no separate
   dark-mode block needed here.
   !important on the visual properties is load-bearing, not decoration: the
   TomSelect CDN's own stylesheet is a <link> tag too, and on every page that
   uses it, it's declared AFTER main.css's <link> in <head> — so at equal
   specificity its bundled defaults (white background, near-black text)
   silently win the cascade and this whole block does nothing. Confirmed by
   loading the real CDN CSS (not a test stub) and inspecting computed style:
   .ts-dropdown resolved to TomSelect's own color, not var(--text). Refusing
   to depend on every page getting <link> order right forever. */

   instead of sharing the same line — confirmed by measuring .ts-control's
