/*
 * Wander — website styles.
 * The app's design system (../DESIGN.md) on the web: a dusk field notebook,
 * a hand-inked trail on deep water. Hairlines carry elevation; there are no
 * shadows, no gradients, no blur. Nothing is centred — everything hangs off
 * one left rail. No web fonts: New York and SF on Apple devices, a plain
 * serif and the system sans elsewhere, so the site fetches nothing.
