/* relief-design — web fonts
 * Inter (400/500/600/700/900): the Latin face for everything — body, labels,
 *   and the display sizes. A neutral grotesque is the right choice here because
 *   this skill draws TECHNICAL diagrams: register names, addresses and signal
 *   labels sit next to prose, and a face with personality would fight the
 *   monospace beside it. The 900 weight is what carries the big headings —
 *   relief has no separate display face on purpose (see design-tokens.md §2).
 * Noto Sans SC (400/500/700/900): the Chinese pairing for Inter, per
 *   cross-skill-rules §H (sans display + sans body → Noto Sans SC). Also the
 *   face that actually sets every Chinese heading, since Inter has no CJK
 *   coverage at all — expected, not a fallback accident.
 * JetBrains Mono (400/500/700): register fields, addresses, clock frequencies,
 *   signal names, bit numbers. In a hardware diagram the mono face is not
 *   decoration — it is what says "this string is a literal from the datasheet".
 *   CJK monospace is rare; Chinese inside a mono span falls back to Noto Sans SC
 *   by the stack below, which is the §H-sanctioned behaviour.
 *
 * NOT loaded on purpose: no rounded display face. An early draft set the
 * headings in a rounded gothic to chase the clay look of the reference images;
 * at 900 weight Chinese glyph counters close up and the heading turns to mush
 * (measured — see dos-and-donts.md §1). The rounded feel in this skill comes
 * from border-radius and the shadow pair, never from the typeface.
