/*
 * Self-hosted Inter Variable font (latin subset).
 *
 * Inter Variable: rsms.me/inter, MIT license. Single woff2 file ~46KB latin
 * subset (vs Montserrat regular + bold ~60KB). Variable fonts allow
 * every weight 100-900 from a single file -> zero extra round trips.
 *
 * Setup (one-time):
 *
 *   curl -sL -o tools/resources/fonts/inter-var-latin.woff2 \
 *     'https://cdn.jsdelivr.net/npm/@fontsource-variable/inter@5.0.16/files/inter-latin-wght-normal.woff2'
 *   ~/.local/venvs/fonttools/bin/python tools/resources/scripts/map-inter-arrows.py
 *
 * The second step maps U+2190/2192/2194/21D2/21D4 to the arrow glyphs the
 * subset already carries for its ligatures: without it those characters come
 * from a system font, a different one on every machine (BUILD.md section 5).
 *
 * Replaces Montserrat. Old pages referencing 'Montserrat' in the
 * font-family get Inter as the first match thanks to the fallback chain.
 *
 * font-display: swap avoids FOIT while keeping rendering fast.
