/*
 * The public site. Palette, type and layout language come from docs/persona.md, section 6.
 *
 * Theme: the reader's system setting decides, unless they have chosen Dark or Light with the
 * switcher in the footer. The choice is kept in localStorage (never a cookie, so the site still
 * sets nothing and needs no banner) and applied by /site/theme.js before the first paint.
 * With no JavaScript the switcher is not shown and the system setting still rules, in CSS alone.
 *
 * Two shades here are derived rather than taken from the persona, both for readability on the
 * light ground: --ink-quiet is a darker secondary ink (the persona's #75687a falls just under
 * 4.5:1 on paper), and --edge gives a card an outline, because the light card and the light
 * ground are a shade apart. --accent-ink is the apricot darkened until it can carry text on
 * paper, used where the accent is type rather than a ground; on a light accent ground the text
 * is the palette's own aubergine, not its cream, which the cream cannot manage at 2.8:1.
 * Everything else is the persona's own.
 *
 * Nothing here is built by Vite: the production image never runs npm, and a marketing page that
 * depends on a build step is a page that breaks on a deploy.
 *
 * Fonts are served from this origin. Nothing on this site is loaded from a third party, nothing
 * is measured, and no cookie is set, which is why there is no cookie banner.
