/*
 * BikeLife website. One stylesheet for every page.
 *
 * The look is the app's: its electric blue, its ink, its page tones (light and
 * dark, from src/constants/theme.ts), its wave, and type that echoes the
 * BIKELIFE wordmark (Archivo, heavy, italic, expanded).
 *
 * Shape rule, as in the app: anything you press is a pill (or a circle when it
 * is only an icon). Everything else is square. Phones are hardware and keep
 * their corners.
 *
 * Motion: ease-out curves, transform and opacity only, exits faster than
 * entrances, and nothing moves when a visitor asks for reduced motion. Nothing
 * animates on hover.
