frontend-browser-caching

The code implements normal browser and CDN caching behavior and shows no evidence of malware, exfiltration, backdoors, or obfuscation. It has a significant cache-isolation warning: Authorization and language headers should not be assumed to partition Cache Storage entries, and generic API/page caching can expose personalized responses unless only explicitly public responses are cached. Use separate cache names or URL keys per context, honor private/no-store directives, restrict methods and routes, and await cache-warming writes.
