setTab(activeTab) runs synchronously during tab wiring, before the `let feedLoaded` / `let telemetryLoaded` declarations further down in the script. If activeTab was 6 (feed) or 7 (telemetry) from a cached silo-tab localStorage value, the short-circuit check `!feedLoaded` hit the temporal-dead-zone and threw: Uncaught ReferenceError: Cannot access 'feedLoaded' before initialization Moved both declarations up to sit above setTab, leaving comment stubs at the old sites.
