/*
 * modelsauce.com — the website's one stylesheet (2026-11-11).
 *
 * The app's look, from the PWA's app.css: its dark violet palette, its two
 * typefaces and the logo's spectrum. The fonts are served from this site
 * (fonts/, copied from the PWA's @fontsource packages, Latin subset, which
 * covers French), so a visit asks nothing of Google or anyone else: no
 * third-party request, as the privacy policy says.
 *
 * Two languages in one page: every piece of text exists in both, marked
 * data-l="fr" / data-l="en", and the one not chosen is hidden by the rule
 * below. lang.js chooses, from a saved choice or the browser, before the
 * page is drawn; French is the default, also without script.
