/* NoteFusion Web — the night design, as on the phone app.
 *
 * Loaded after theme.css and app.css on /app and /app/sheet only (the marketing pages keep their own
 * look). It carries the mobile app's palette (mobile/src/design/theme.ts: `darkColors` / `night` for
 * Night, `colors` for Day), its type (Geist for the interface, JetBrains Mono for solfa) and its
 * shapes (12px buttons and fields, 20px cards), and the house press: a control under the finger
 * scales to 0.97 in 150ms and never bounces. Day is the default; Night is one switch away. Blue is
 * flat — no gradients, no glows — so the music, not the chrome, is what catches the eye. */
