/* Aly Market — Shared UI Components
 *
 * Mobile-first primitive classes (.aly-card, .aly-btn, .aly-input, etc.)
 * that all 3 web frontends can use directly. Pair with tokens.css.
 *
 * Naming: every class starts with `aly-` so it never conflicts with
 * Tailwind utilities or framework styles. Each class maps cleanly to a
 * Flutter widget (Card, FilledButton, TextField, Chip, ...).
