Currently, with STATAMIC_STATIC_CACHING_STRATEGY set to full, log file entries warn the setup isn't quite right:

{"message":"Static cache loaded [URL REDACTED] If you are seeing this, your server rewrite rules have not been set up correctly.","context":{},"level":100,"level_name":"DEBUG","channel":"production","datetime":"2025-07-25T20:38:22.416878+00:00","extra":{}}
