/*
 * Dark theme, with the type, icons, corners and spacing of my apps (Shop Weh):
 * Inter for everything you read and tap, Source Serif 4 for titles, Phosphor icons.
 *
 * Radius scale, outer to inner: cards 20px > tiles inside cards 10px.
 * Every standalone control (button, chip, nav link) is a pill.
 * Spacing runs on 4px steps: 4, 8, 12, 16, 24, 32, 48, 64.
