speedtest_worker.js uploads in 20 MB chunks by default (xhr_ul_blob_megabytes: 20) but the official Docker images inherit PHP's stock post_max_size = 8M / upload_max_filesize = 2M, so every upload chunk: * triggers a "POST Content-Length ... exceeds the limit" warning (leaked into the response body of /backend/empty.php on the Debian variant where display_errors is on; suppressed but still emitted on Alpine where it's off); * causes empty.php's subsequent header() calls to fail with "Cannot modify header information - headers already sent", leaving the response without proper status, cache, or CORS directives. Ship a small docker/librespeed-php.ini with post_max_size = 32M, upload_max_filesize = 32M, memory_limit = 256M and COPY it into the right conf.d for each base image (/usr/local/etc/php/conf.d on Debian, /etc/php84/conf.d on Alpine). 99- prefix follows the NN-name.ini packaging convention so this loads after distro defaults but never silently shadows operator overrides. Verified post-fix on both variants: a 20 MB POST to /backend/empty.php returns HTTP 200 / 0 bytes with no warning leakage.
