"""Refuse to start a download that could fill the volume.
This machine's root filesystem was at 98% (90 GB free) when this plan was written, with a
1.2 TB Hugging Face cache belonging to other work. Filling it would damage unrelated
projects.
This script REPORTS and EXITS. It never deletes, prunes, or relocates anything: reclaiming
space is a human decision, and an automated tool guessing which gigabytes are expendable is
exactly how someone's dataset disappears.
