+## PHP upload tuning
+Apache uses `mod_php` (not FPM). Limits raised from distro defaults in both `/etc/php/8.4/apache2/php.ini` and `/etc/php/8.4/cli/php.ini` (the latter so `occ`/cron honor the same):
+
+| key | value |
+|---|---|
+| `upload_max_filesize` | `16G` |
+| `post_max_size` | `16G` |
+| `memory_limit` | `512M` |
+| `max_execution_time` | `3600` |
+| `max_input_time` | `3600` |
+| `output_buffering` | `0` |
+
+Reload Apache after edits: `systemctl reload apache2`. Caddy in front (`cloud.hubris.network`) imposes no body-size limit, so these are the effective ceiling.
