/**
 * Self-hosted webfonts: the four families of the approved homepage design (docs/design/artifact-home), as the design
 * loads them from Google Fonts, served from this theme. @font-face rules only.
 *
 * Source: the design's two Google Fonts stylesheets, fetched 2026-10-08 with a current Chrome user agent:
 *   css2?family=Bricolage+Grotesque:opsz,wdth,wght@12..96,75..100,200..800&family=Geist+Mono:wght@400..600
 *        &family=Instrument+Serif:ital@0;1&family=Inter:opsz,wght@14..32,400..700&display=swap
 *   css2?family=Noto+Sans+Bengali:wght@400..700&text=%E0%A7%B3&display=swap   (the taka sign only)
 * Every face and unicode-range below is Google's, byte-identical files renamed <Family>-<subset>.woff2. The files are
 * variable: Bricolage Grotesque v9 (opsz 12-96, wdth 75-100, wght 200-800), Inter v20 (opsz 14-32, wght 400-700), Geist
 * Mono v6 (wght 400-600); with font-optical-sizing at its default (auto) the optical size follows the font size, as in
 * the design. Instrument Serif v5 (regular and italic). All SIL Open Font License 1.1. A browser fetches a subset only
 * when the page uses one of its characters. The two preloaded files (BricolageGrotesque-latin, Inter-latin) are
 * requested by inc/enqueue.php with the same URLs as below, so keep the paths in sync.
