v4.21.0 — Pit Wall Check

A pit-wall check on multi-tab uploads — every car gets its owner confirmed before it rolls out. 🚦 🔑 Your uploads only ever go to YOUR garage • Before the queue sends any photo — even one still held in the tab's memory — it re-confirms who's signed in right now and that the shot was queued by that same account. If they don't match, the car parks on pit road instead of being sent under the wrong login 🔄 Switch accounts on a shared device and the tabs keep up • Signing out or swapping accounts in one tab now flags every other open tab on the spot — an upload mid-send is waved off and anything still queued parks, so a hand-me-down laptop never mixes two collectors' cars 🔧 Under the hood • A stale tab can no longer ride an old login: the drain reads the live session fresh from the server for every send, and offline queueing for your own account still drains the moment you're back online
