/* ────────────────────────────────────────────────────────────────────
 * Spartan CRM — Email reminders top bar (WIP-V2.1-EMAIL-INTAKE-01)
 * Companion to modules/38-email-reminders-bar.js
 *
 * Pulse escalates by day-count:
 *   Day 0-1  → .er-pulse-normal   (2.4s red pulse, normal banner)
 *   Day 2    → .er-pulse-super    (1.4s super-red pulse, thicker border)
 *   Day 3+   → .er-pulse-fullscreen / .er-pulse-extreme
 *               full-screen red overlay + 1.0s pulse on the banner
 *               body.er-fullscreen-active locks the screen until the
 *               user resolves, snoozes, or dismisses the overlay
 *
 * All gated by prefers-reduced-motion: reduce.
