/* The three faces the site is drawn in, served from here.

   They used to come from fonts.googleapis.com: a render-blocking
   stylesheet on a third-party origin, which then pointed at a second
   third-party origin for the files themselves. Two DNS lookups and two
   TLS handshakes stood between a phone on a venue car park's 4G and the
   first word of the page, and every one of those requests told Google
   who was reading. There are no third-party fonts or stylesheets on
   colabroom.com now. It is not down to zero hosts — a page still calls
   our own Supabase function for the counters and the tool, and the
   noindex flier page still pulls a QR library from cdnjs — but nothing
   a visitor does not need is on the critical path any more.

   These are the same files Google serves, byte for byte, taken from the
   same API on 20 September 2026. All three are under the SIL Open Font
   License 1.1, which permits exactly this; the licence and the copyright
   notice for each one sit beside the files in fonts/.

   Only the latin and latin-ext subsets are here. Google's stylesheet
   also offers vietnamese, greek and cyrillic, which an English-only site
   can never use — the browser was already skipping them, and now they
   are not on the domain at all.

   The weight ranges are the union of what the pages ask for: Archivo
   500-900, Newsreader 300-500, JetBrains Mono 500. Each family is one
   variable file per subset, so a page that uses five Archivo weights
   downloads one Archivo.

   To refresh: fetch the css2 URLs below with a current browser's user
   agent, save the latin and latin-ext woff2 files over the ones in
   fonts/, and check the unicode-range lines still match.
