/*
 * Self-hosted webfonts.
 *
 * Owner's decision, 2026-08-08: no fonts.googleapis.com. These files ship in
 * the repo, so no third-party stylesheet, script or font is loaded. Mercury's own
 * `mercury-googlefonts` handle (which pulls Roboto, a face the design spec
 * never uses) is dequeued in functions.php.
 *
 * All three families are SIL Open Font License. Licence texts sit alongside
 * the woff2 files in ../fonts/.
 *
 * Latin subset only, per sms-design-tokens.md §2. woff2 only — every browser
 * that matters has supported it since 2016, and a woff fallback would double
 * the payload for browsers that will never request it.
 *
 * `font-display: swap` per the spec: text paints immediately in the fallback
 * and reflows when the webfont lands. For a reference site, readable-now beats
 * pixel-perfect-later.
