/* ===== Notification System — Tiers 1, 3, 4 =====
   Tier 1: Toast       — top-center slide, auto-dismiss
   Tier 3: Transmission — center overlay, acknowledgment required
   Tier 4: Purge Confirm — destructive action, two-button confirm
   (Tier 2 Droid Alert stays in main.css until visual-overhaul plan)
