/*
 * Sarthe site — shared design system.
 *
 * Tokens mirror src/constants/theme.ts exactly, including the one rule that
 * is easy to get wrong: `--accent` is the brand gold and is only ever a
 * FILL. As text on white it lands near 1.7:1, so light mode uses the bronze
 * `--accent-text` for anything read as words. Against near-black the gold
 * clears 9:1, so dark mode uses the real thing for both.
 *
 * Light and dark both ship because the app itself does. The phone mockups
 * are the exception — they always render the app's dark theme, since they
 * depict a device with its own UI rather than part of this page.
