/*
 * Self-hosted webfonts.
 *
 * These used to come from fonts.googleapis.com and api.fontshare.com. Serving
 * them ourselves removes a third-party dependency from every page render (a
 * failed fetch leaves headings in the fallback face until a reload), drops four
 * preconnects and two cross-origin stylesheet requests, and keeps visitors' IP
 * addresses off a third party, which matters more now that the site markets to
 * readers in the EU.
 *
 * The shared-cache argument for font CDNs no longer applies: browsers partition
 * the HTTP cache by top-level site (Chrome 86, Firefox 85, Safari earlier), so
 * a font fetched on another site is never reused here.
 *
 * vercel.json already serves *.woff2 with Cache-Control: max-age=31536000.
 * Filenames are therefore treated as immutable. Replacing a font means writing
 * a new filename, not overwriting one of these.

/* --------------------------------------------------------- Cabinet Grotesk */
/*
 * The four weights api.fontshare.com was serving, taken from the official
 * download's Fonts/WEB/ folder unmodified. Same 405 characters as the CDN
 * build, verified by reading the cmap out of both.
 *
 * Discrete weights rather than the variable file that also ships in that
 * download, even though the variable one is 41 KB against 81 KB for these
 * four. Two reasons. A browser only ever fetches the weights a page actually
 * matches, so the four statics usually transfer less than the variable file
 * would. And declaring a 100 to 900 axis would restyle the site: Fontshare
 * declares 400, 500, 700 and 800, so an element at font-weight 600 currently
 * snaps to 700, and on a continuous axis it would render at a true 600.
 *
 * Licence: this is NOT an open font. See cabinet-grotesk-FFL.txt, and the
 * memory note, before reusing these files anywhere else.

/* ------------------------------------------------------------------ Nunito */
/*
 * Nunito is a variable font. Google serves one file per unicode-range subset
 * and reuses it across every weight, so `wght@400;500;600;700` was four
 * @font-face blocks pointing at the same bytes. One block per subset here.
 *
 * The file's wght axis runs 200 to 1000, but the declared range is 400 to 700
 * because that is what Google was declaring. Widening it would change how the
 * site renders: elements at font-weight 800 currently match the 700 face and
 * are drawn at 700, and on the full axis they would suddenly be drawn at 800.
 * Moving where the fonts are served from should not restyle the page.
 *
 * Cyrillic, Greek and Vietnamese subsets are deliberately absent. Nothing on
 * the site is written in those scripts, and unicode-range means a browser only
 * fetches a subset it needs, so latin-ext costs nothing to keep as insurance
 * for place names in the travel posts.
