/* Minibyte — shared styles for the site at minibyte.app.
 *
 * The palette is copied verbatim from the app's own DesignSystem.swift rather than invented,
 * so the page and the product read as one thing. Terracotta means "act on this" here exactly
 * as it does in the app; green is reserved for bytes that have actually gone, never a
 * forecast. If a token moves in Swift, move it here.
 *
 * Three surfaces, same as the app: ground (the page) → sunken (chips, tracks, passive notes)
 * → surface (raised cards), plus the accent card, which appears once on the whole site.
 *
 * Type is the system stack on purpose. The app ships SF Pro, and -apple-system renders real
 * SF on every device a visitor is likely to be holding — a closer match than any webfont,
 * and nothing to download.
