/* Auth modal — sign in / create account / forgot password.
 *
 * Visual language matches the search-page card chrome:
 *   - white card on a translucent ink scrim,
 *   - 22 px radius + multi-layer shadow (mirrors `.compose`),
 *   - Inter Tight typography with tight tracking,
 *   - greys via `var(--ink-rgb)` alpha so we get a consistent fade
 *     across light/dark themes.
 *
 * Markup contract is in `web/search.html` (`<dialog id="authModal">`)
 * and `web/lib/auth-modal.js` flips the modal's `data-view`
 * attribute between login / signup / forgot.
