 * Clear handle.me site data, as the handle.me footer does — plus IndexedDB and shared-domain

 * Cross-subdomain reality: the browser's same-origin policy makes it IMPOSSIBLE for JS on
 * `merch.handle.me` to clear `preview.hal.handle.me`'s localStorage / sessionStorage / caches —
 * those are origin-scoped. What CAN be cleared cross-subdomain are cookies scoped to the shared
 * parent domain (`.handle.me`), which this does. True cross-subdomain storage wipe would require
 * each subdomain to clear its own (e.g. a hidden-iframe broadcast to a shared clear page); that's
 * a deliberate future addition, not something achievable from one origin.
