/* Website stylesheet.
 *
 * Hand-written CSS, no build step and no framework — the repository has no
 * Node toolchain and this site is small enough to stay that way.
 *
 * Every colour, type size and measurement comes from `tokens.css`, which is
 * GENERATED from the app's own ThemeData (see site/sync-theme.sh). Nothing in
 * this file may hardcode a colour: the point is that the site and the app share
 * one palette rather than two that drift. Dark mode needs no rules here either
 * — the tokens swap themselves under `prefers-color-scheme`.
 *
 * The component rules below deliberately mirror the app's widget themes
 * (elevatedButtonTheme, cardTheme, chipTheme, inputDecorationTheme, appBarTheme
 * in app_theme.dart): pill controls 52px tall, flat cards defined by a thin
 * outline rather than a shadow, stadium chips, filled inputs with a 2px focus
 * ring.
