+// Off-main-thread nostr event verification. Schnorr signature checks (real
+// secp256k1) on a relay backlog blocked the UI on boot / when a community
+// opens — the carousel-stutter cause a CPU profile pinned to verifyEvent. This
+// worker does that work on another thread; the main thread posts events and
+// gets back a boolean per event, so the page never freezes on a burst.
+//
+// Bundled to dist/verify-worker.js (see build.js) and loaded as a classic
+// Worker. Same verifyEvent nostr-tools uses on the main thread, so semantics
+// are identical — this only moves WHERE it runs.
