/* Brand typefaces, self-hosted.
 *
 * WHY THIS FILE EXISTS. The design system names Montserrat Bold, Albert Sans Light and
 * IBM Plex Mono, and the room's CSP is `font-src 'self'` — so a CDN link is not an
 * option, and without these files every viewer saw the fallback stack. The room had the
 * brand's colours and none of its typography, which is most of what a brand actually is.
 *
 * LICENSING. All three families are SIL Open Font License 1.1, which permits
 * self-hosting and redistribution. See LICENSES.md beside this file.
 *
 * SUBSETTING. Montserrat and Albert Sans ship here as VARIABLE fonts — one file covers
 * the whole weight range the room uses, instead of one file per weight. IBM Plex Mono
 * has no variable cut, so its three weights are three files; it is only ever used for
 * figures, dates and version strings, so it carries the latin subset alone.
 * Montserrat's latin-ext subset is deliberately absent: it is 70KB and only headings use
 * the face, which are English. Albert Sans keeps latin-ext, because body copy is where
 * an accented name would appear.
 *
 * font-display: swap — text paints immediately in the fallback and swaps when the face
 * arrives. A room that shows nothing until a font downloads is worse than one that
 * reflows once.
