/*
 * The documentation site's whole stylesheet.
 *
 * The accent is NativePHP's own: the two colours in upstream's application icon are a slate
 * blue (#54608D) and a teal (#4CABAD), taken straight from resources/build/icon.png rather
 * than guessed at. The teal is darkened to #0f7378 in light mode, where the brand value only
 * reaches 2.71:1 against white — below the 4.5:1 that body-sized link text needs — and used
 * as-is in dark mode, where it clears 7:1. The logo carries both colours unaltered.
 *
 * No external requests: system fonts, an inline SVG favicon, no CDN. A documentation site
 * that cannot render offline renders differently for whoever is behind a corporate proxy,
 * and this one gets read while something is broken.
 *
 * Three theme states. Tokens are defined for light on :root, redefined for dark under
 * prefers-color-scheme (guarded so an explicit light choice wins), and redefined again under
 * [data-theme="dark"] so the toggle wins in both directions. No colour is ever declared only
 * inside a media query — a page always has a complete palette.
