/*
 * Self-hosted fonts.
 *
 * Served from this origin rather than Google's, because the audience is on low-end
 * Android over mobile data: a third-party font host costs a DNS lookup, a TLS
 * handshake and a second connection before the first Bangla glyph can paint. It also
 * means no request to a third party is made on a customer's behalf.
 *
 * Only what this site renders is shipped. Inter is the variable build, so its whole
 * 400–700 range is one 47 KB file instead of four static ones, and only its `latin`
 * subset — `latin-ext` is Eastern European diacritics that never appear here, and is
 * larger than `latin` itself. Hind Siliguri has no variable build, so its four weights
 * stay separate, and only `bengali` is shipped: Latin inside a Bangla element falls
 * through to Inter, which is what the design asks for anyway.
 *
 * `font-display: swap` throughout — text in a fallback face is readable; invisible
 * text is not.
 *
 * Both families are SIL Open Font License 1.1, which permits self-hosting.
 *
 * Regenerate by re-running the phase 8 font step; do not hand-edit the unicode-range
 * values, which are what stop a Latin-only page downloading the Bengali file.

 * semibold file answer a 500 request with a real glyph rather than a synthesised one,
