/* frontend/css/alerts.css — Phase C
 *
 * Alerts settings panel (inside the Settings overlay) + inline
 * mini-subscribe form on the ticker page. Consumes only existing
 * theme tokens — no hardcoded hex values, no new tokens.
 *
 * Layout follows design § 8.1.1 (FR-A3 / ISSUE-010):
 *   ≥ 1024 px : two-column form (master toggles | subscription list)
 *   640–1023  : single column; per-ticker list collapses with View all
 *   < 640 px  : single column; sticky CTA on mobile
 *
 * Tap-target floor at < 640 px is 44 × 44 (WCAG 2.5.5) — mirrors the
 * calendar chip rule. Reused from app.css buttons where possible.
