/* Protect Trans Kids Colorado — site.css
 *
 * External stylesheet, never an embedded block: one file, one place to change,
 * and it caches. (OPERATIONAL_RULES web rule 1 — no CSP exception applies here,
 * this is a self-hosted page that can fetch a second file.)
 *
 * There is no JavaScript on this site and the CSP enforces that, so everything
 * below is CSS-only. Theme follows prefers-color-scheme; there is no toggle,
 * because a toggle needs either script or a hack that costs more than it earns.
 *
 * THEME STRATEGY. The hero is a FIXED dark field in both themes, like a printed
 * poster, with its own fixed foreground tokens. Colors that do not invert
 * between themes need a pinned foreground or one theme fails — the ivory-on-gold
 * class of bug. Everything below the hero adapts.
