+/**
+ * Regression for the Passport-personal-access-tokens permission
+ * bypass. Passport's default routes at /oauth/personal-access-tokens
+ * are auto-registered by its service provider with only web +
+ * auth:web middleware, so any user with a valid session cookie could
+ * POST and mint a long-lived bearer token even if their self.api
+ * permission had been revoked.
+ *
+ * The fix registers overriding routes at the same URIs in
+ * routes/web.php (which loads before Passport's package service
+ * provider boots, so FIFO route resolution picks ours) with the
+ * `can:self.api` gate added. Authorized users still hit the same
+ * PersonalAccessTokenController Passport would have used.
