 * Mindroll — the website.
 *
 * The colour tokens this file uses are written by `scripts/build-site.mjs` into
 * `tokens.css` from `src/brand/brand.json`, so the site cannot drift from the
 * app's palette. Nothing here hard-codes a brand colour: where a tint is needed
 * it is mixed from a token, against the `--wash-base` that flips with the
 * colour scheme.
 *
 * No webfont, on purpose. The app sets its headings in the system serif — New
 * York on Apple platforms, Iowan Old Style or Georgia elsewhere — so using the
 * same stack means the site matches the app exactly on the devices its readers
 * are holding, with no download, no layout shift, and no third party in a
 * privacy policy that currently names none.
 *
 * The ground is white and the type is serif, which is the whole of the look:
 * the page is quiet, the headings carry the personality, and the colour is
 * spent in three places — the accent, the tile hues, and the closer — rather
 * than sprayed across every surface.
