tiennm99 2f4efd1cab feat(tab-lock): single-tab guard via BroadcastChannel ...

Two tabs of the app on the same origin both running auto-call would
double-draw, double-write `loto_master`, and overlap audio. New tab
now broadcasts a claim; old tab freezes itself with a fullscreen
overlay ("Loto đã mở ở tab khác. Tap để chuyển về tab này.") and the
user can tap to take it back — handover broadcasts a fresh claim,
freezing the other tab in turn.

Mounted in +layout.svelte's onMount so the cleanup closes the channel
on HMR / route changes. No-op in legacy iOS Safari (≤15.4) without
BroadcastChannel — silently falls through to the prior behavior.
