/*
 * Self-hosted Inter — replaces fonts.googleapis.com to remove the
 * third-party round-trip + DNS lookup + cookieless-origin handshake.
 *
 * Files are downloaded from Google Fonts (v20, Latin + Latin-Ext subsets).
 * Both subsets share a single woff2 URL per subset across all 6 weights;
 * the browser fetches each file once and treats it as six weight variants.
 *
 * [claude:opus-4.8-1m][client:2.1.195][hurc:v0.12.267] font-display: swap (was `optional`).
 *   `optional` gives a ~100ms block window and NO swap period: whichever face
 *   (Inter or the fallback) wins the FIRST paint is frozen for the entire
 *   pageview and never swaps. Measured consequence — the weight-800 hero
 *   headline lost that race nondeterministically, so it rendered in Inter on
 *   some marketing pages and in the system font on others ("different font on
 *   every page"). Compounding it, the metric-matched 'Inter Fallback' below is
 *   src: local('Arial') — Arial is absent on Linux, so the frozen fallback
 *   dropped PAST it to -apple-system, a visibly different typeface at the same
 *   px size.
 *   `swap` renders the metric-matched fallback immediately, then ALWAYS swaps
 *   to Inter once the (preloaded) woff2 arrives — so every page converges on
 *   Inter. The fallback is metric-matched (see 'Inter Fallback' overrides
 *   below), so the swap is layout-stable: glyph box sizes are identical and
 *   buttons / headings do not reflow.
 *
 * Fallback metrics sourced from next/font/google output for Inter+Arial
 * (90.20% ascent, 22.48% descent, 0% line-gap, 107.40% size-adjust) — the
 * canonical metric-match for Inter that Vercel publishes.
