With no mirror configured the dialog was titled "Download the SAM 3
Model?", only said to put "the files" in the folder (see
docs/ai-masks.md) and offered Close. It is now titled "Install the SAM 3
Model", names the three files (model.safetensors, vocab.json,
merges.txt from facebook/sam3), and has a Show in Finder / Explorer /
File Manager button that creates and shows the model folder, plus a link
to the installation guide. Object and Describe work as soon as the files
are there.
The download location itself (a hosted mirror) is still a maintainer
decision: DEFAULT_MIRRORS stays empty.
