 Notes 
 
 The original Cloud Run 504 wave was intermittent and not conclusively root-caused in API code. 
 Live API recovered before this patch, and post-deploy logs remain clean. 
 This patch prevents the user-facing login button/page from hanging indefinitely if API/CORS requests hang again. 
 
 Operational caveat 
 The original API 504 burst was intermittent and recovered before the web resilience patch was deployed. The deployed client-side fix prevents indefinite login/API hangs and surfaces recoverable errors if an upstream API/CORS request hangs again. Post-deploy Cloud Run 5xx/504 logs were empty for the checked window.
