[e2e-failed] gerchowl/mat-vis-tst: e2e failed

[github-actions]

e2e failed for gerchowl/mat-vis-tst (event: schedule).

• Run: https://github.com/MorePET/mat-vis/actions/runs/25098757332

Likely causes: HF transient (rate-limit or 5xx), upstream polyhaven API hiccup, or a regression in the per-file substrate. The Python E2E suite cleans up its throwaway tag on teardown — failed runs may leave the tag behind on mat-vis-tst; safe to delete manually.

Opened automatically by .github/actions/notify-on-failure.
It will not re-open if already present; comments are added on recurrence.
