Parents get a real push notification when a kid checks off a task (false->true transitions only, fire-and-forget, degrades gracefully with no VAPID keys configured). Dashboard is a fully installable iOS/Android PWA; each child's kiosk link gets its own dynamic per-token manifest so "Add to Home Screen" opens straight into their board in standalone mode. Kiosk view is reworked for tablets: safe-area-aware full-bleed layout, the whole task row is now tappable (previously only the 24px checkbox was, well under Apple's touch-target minimum), and app icons are generated by a small dependency-free PNG encoder (no image tooling available in this environment). Push requires real HTTPS (iOS Safari won't allow it otherwise) - README and UNRAID.md cover VAPID setup and the HTTPS prerequisite.
