Queue workers
Watermark application
Default branding is prompt-instructed AI text; admins can disable it per job; a separate Imagick/GD path exists in a nowatermark-named worker.
Implemented Verified from source User-facing
In one sentence
Most workers ask the model to render corner branding text unless the queue watermark flag is off; another worker may physically composite a logo with Imagick.
Important nuance
arcana.queue.processor.cron.nowatermark.php still attempts physical logo watermarking in save_base64_image() — the filename is misleading relative to its behavior.
