/* ---------- [TOKENS] theme tokens — "Kotlin Sunrise, Editorial Cut" ----------
   Light is the base palette on :root. Dark is applied either by the
   system preference (prefers-color-scheme) or by an explicit
   data-theme="dark"/"light" attribute set via localStorage, which
   always wins over the media query. Both palettes are tuned on their
   own — no inversion filters, no pure #000/#fff.

   Every text-bearing color below has been contrast-checked against the
   surface it's actually used on (WCAG relative-luminance formula) and,
   where the "swatch" version of a brand color failed, a separate
   darker/brighter *-text-safe variant was derived instead of diluting
   the brand color itself. --accent-2 carries coral (text-safe shade);
   the brighter coral used for large fills/tags lives in --coral-swatch. */
