/**
 * IRAMA styles.
 *
 * Constraints that shaped this file:
 *   - One-handed layouts (design §7). Primary actions sit in the lower third,
 *     within thumb reach; headings sit at the top where nothing needs tapping.
 *   - No reliance on colour alone (§7). Every state that is shown with colour is
 *     also shown with size, shape, or text.
 *   - Reduced motion is honoured both from the OS and from in-app settings.
 *   - Nothing pulses, nudges, badges, or demands attention. There is no red
 *     anywhere in the app except the crisis affordance.
