/*
 * The whole site's stylesheet.
 *
 * Colours and radii are never written as literals here — they come from the
 * custom properties in src/theme.ts, which imports the app's own design tokens.
 * A hex typed into this file is a silent fork of the design system, which is
 * the exact failure CLAUDE.md's token rule exists to prevent. The only literal
 * colours below are neutral alphas (shadows, overlays) that have no token.
 *
 * No CSS framework, no reset library: the site is six pages, and a normalize
 * step small enough to read is worth more than a dependency to update.
