/* Everyvore's public shell.
 *
 * Hand-written CSS rather than the app's Tailwind build, because these two pages must render
 * without a build step and without JavaScript. `/bot` in particular is read by a webmaster
 * deciding whether to block us, quite possibly in a text browser or with scripts off, and an
 * obligation discharged only when a bundle resolves is not discharged.
 *
 * Tokens are copied from `apps/web/src/index.css` (ADR-019) rather than imported. Two copies is a
 * real cost; the alternative is coupling a static page to a Tailwind pipeline it does not
 * otherwise need. If the palette moves, move it here too.
