/* fonts.css — self-hosted Inter (variable, latin subset).
 *
 * WHY: the whole app asks for `font-family: Inter, ui-sans-serif, system-ui, …`
 * but Inter was never actually loaded, so each OS substituted its own UI font.
 * macOS fell back to San Francisco (a VARIABLE font → the `font-weight: 850/900`
 * chords rendered exactly), while Windows fell back to Segoe UI (STATIC weights
 * → the browser SYNTHESISED a bold, which reads heavier and tighter). Chords
 * like `B♭m/F` therefore looked "too bold / too cramped" on Windows only.
 *
 * FIX: ship Inter ourselves as a genuine VARIABLE font (wght 100–900) so the
 * heavy chord weights are rendered — never faked — identically on every OS.
 *
 * The family name stays `"Inter"` (not "Inter Variable") so every existing
 * font stack in the app picks it up without touching a single selector. If the
 * file ever fails to load, the untouched fallback chain still applies.
 *
 * `unicode-range` is the exact latin coverage of this file; glyphs outside it
 * (e.g. the ♭/♯ accidentals, which the score deliberately draws in Georgia)
 * keep flowing to the next family in the stack, exactly as before.

/* Accidentals — ♭ (U+266D), ♮ (U+266E), ♯ (U+266F).
 *
 * Inter ships NO music glyphs (confirmed: neither the latin subset nor the full
 * 2849-glyph Inter has U+266D), and the score's `.chord-accidental` asks for a
 * serif family (Georgia / Times New Roman) that ALSO lacks them. So the flat and
 * sharp used to fall through to whatever symbol font the OS happened to supply:
 *   • macOS   → Hiragino Mincho ProN
 *   • Windows → Segoe UI Symbol
 * i.e. a DIFFERENT glyph on each platform — the remaining `B♭m/F` mismatch.
 *
 * This tiny (876-byte) Noto Serif JP subset pins ONE shape everywhere. It is a
 * mincho face, the same style macOS already fell back to, so the macOS look is
 * preserved while Windows now matches it. It is registered on the SAME "Inter"
 * family (disjoint unicode-range) so EVERY ♭/♯ in the app — chord tokens, key
 * names, everything — resolves through it. Declared `font-weight: 100 900` so the
 * glyph is used as-is at any weight (never faux-bolded). OFL 1.1. */
