/* Tally — the website.
 *
 * The palette and the three typefaces are LIFTED FROM src/ui/tokens.css, not chosen here. The site
 * and the extension should read as one thing, and the token file is the authority: its values carry
 * measured WCAG ratios in their comments and are pinned by src/ui/tokens.test.ts. Copied rather than
 * imported because what deploys is the `site/` tree alone, with no build step to resolve a path into
 * src/ — so if a colour changes there, change it here too. Only the tokens the site actually draws
 * are copied; the app has many more.
 *
 * AMBER IS THE ONLY WARM COLOUR, and on this site it is spent in exactly one place: the hero's
 * unlogged figure. That is the same discipline the app keeps, and the same argument — the eye should
 * go to the gap.
