/*
 * Fonts are self-hosted (originally mirrored via fontsource from Google Fonts).
 * Self-hosting removes a third-party origin from the critical path: the fonts now
 * reuse the existing connection instead of paying another DNS + TLS handshake,
 * which is the dominant cost on slow cross-border links.
 * Only the latin subset is shipped (each weight ~11-17KB, fetched on demand).
 * Site copy is Simplified Chinese, so the Chinese glyphs still fall back to
 * PingFang SC / Microsoft YaHei.
