/*
 * One stylesheet for the whole site.
 *
 * The palette is lifted straight from Backstory's design tokens
 * (`src/theme/theme.ts`) so the site and the app feel like one product:
 * Apple-minimal, one confident accent (indigo), semantic colours that flip
 * between light and dark.
 *
 * Rules of the road:
 *  - Colours come from the custom properties below. Never hard-code a hex in a
 *    rule; add a token instead, so light and dark stay in step.
 *  - Mobile first. Most visitors arrive from an App Store listing on a phone.
