/*
 * Vitara Health design system
 * ------------------------------------------------------------------
 * Mobile-first, native-app feel, accessibility-first, classless.
 *
 * The views are semantic HTML with almost no classes, so this file
 * styles ELEMENTS directly. Adding a new screen rarely needs a new
 * class — write plain h1/p/fieldset/label/input/button and it works.
 *
 * Sections:
 *   1. Tokens          — colour, type, space, radius, motion
 *   2. Reset & base    — sane defaults, native scroll behaviour
 *   3. App shell       — the centred phone-width canvas (main)
 *   4. Typography      — headings, body, eyebrow, links
 *   5. Forms           — fieldset, label, text inputs, textarea
 *   6. Choice rows     — radio/checkbox as big tappable cards
 *   7. Buttons         — primary action, sticky native action bar
 *   8. Feedback        — errors / alerts
 *   9. Review table    — the summary screen
 * ------------------------------------------------------------------ */
