/* -------------------------------------------------------------
 * Fonts. The site font "Curio" (theme.json) is two fonts in one family:
 * regular-weight text uses Merriweather and bold text (600+) uses
 * Figtree Extra Bold (a free stand-in for Verywell Health's FS Albert
 * Extra Bold), the same split Verywell uses.
 * "Curio Fallback" mirrors that split with system fonts while the web
 * fonts load (or if they fail), so headings stay sans-serif.
 *
 * The metric overrides make the fallback take the same room as the web
 * font, so text doesn't reflow when it arrives. Computed from the woff2
 * files (fontTools: unitsPerEm, hhea ascender/descender, advance widths
 * weighted by English letter frequency incl. space) against published
 * Georgia and Arial Bold (= Helvetica Bold) metrics:
 *   Merriweather 400: upm 1000, asc 984, desc 273, gap 0, avg width .499 em
 *   Georgia:          avg width ~.444 em  -> size-adjust .499/.444 = 112.5%
 *   Figtree 800:      upm 1000, asc 950, desc 250, gap 0, avg width .4745 em
 *   Arial Bold:       avg width ~.484 em  -> size-adjust .4745/.484 = 98%
 *   ascent/descent-override = web font metric / size-adjust.
 * Tuned for Georgia and Arial Bold; the other local() faces only
 * approximate them.
