+// IMPORTANT: must precede any import that may touch localStorage at module load.
+// Content scripts run in an "isolated world" that shares localStorage with the
+// host page. The dashboard at *.subturtle.app and localhost:3000 (dev) uses
+// `token` as its own localStorage key for the user's session — when the
+// extension's modular-rest client (or our explicit cache write below) writes
+// the extension's anonymous token there, it clobbers the dashboard user's
+// session and bounces them to /auth/login on the next reload or new tab.
+//
+// Block 'token' writes/removes from the content-script side on those origins.
+// The extension already persists tokens to chrome.storage.sync via the
+// background script, so losing the per-page localStorage cache only costs
+// one extra /user/loginAnonymous call per content-script mount on dashboard
+// origins — it does NOT break extension auth.
