/* Self-hosted web fonts — replaces the fonts.googleapis.com stylesheet.
 *
 * Files in ./fonts/ are the Google Fonts woff2 subsets (latin + latin-ext only;
 * cyrillic/vietnamese/symbols subsets are omitted — the site is English with
 * Romanian place names, all of which live in latin + latin-ext).
 * Geist and Geist Mono are variable (wght 100–900), so one file covers 400–800.
 *
 * Each family is paired with a metric-matched fallback face so the swap from
 * fallback to web font does not reflow. Overrides were computed as
 *   size-adjust = (webfont.xWidthAvg / upm) / (fallback.xWidthAvg / upm)
 *   ascent/descent/line-gap-override = (webfont.metric / upm) / size-adjust
 * using @capsizecss/metrics 4.3.0 for the fallbacks and the shipped woff2
 * metrics for the web fonts (verified identical to capsize: Geist 1000/1005/-295,
 * Instrument Serif 1000/990/-310).
 *
 * The Instrument Serif italic fallback is matched against Georgia's roman
 * metrics — capsize publishes no Georgia Italic entry — so it is a close
 * approximation rather than an exact match.
