  "storage": "The page swaps its localStorage for a throwaway store and name-spaces every database it opens to a `pilot-<token>` profile BEFORE it boots, so the session writes nowhere a returning human reads. `window.__pilotStorage` reports the swap; `chart.receipt` names the keys the session wrote.",
