+- Rename inner `strongSelf` in `-setBridge:` to `innerStrongSelf` so it
+  no longer shadows the outer.
+- Gate `#import <React/RCTCxxBridgeDelegate.h>` behind `#if !USE_BRIDGELESS`
+  to match the already-conditional protocol conformance.
+- Drop the stray `;` before the `-viewWithModuleName:initialProperties:`
+  body.
