/**
 * Vite inlines any asset under 4 kB as a `data:` URI. That is a good default
 * for small images and a silent bug for fonts here, because the site's
 * Content-Security-Policy sets `font-src 'self'` — a data: URI is not 'self',
 * so the browser refuses to load it and the glyphs simply never arrive.
 *
 * It only bites the handful of subsets that happen to be small: JetBrains
 * Mono's cyrillic-ext subset is 3.6 kB, so it was inlined and blocked while
 * the other seventeen font files loaded normally. Exactly the kind of failure
 * that hides for a year and then shows up as tofu in someone's name.
 *
 * Returning `false` forces a real file; returning `undefined` leaves Vite's
 * normal size-based decision in place for everything else.
