"""Fetch real benchmark images into /ComfyUI/input via the Wikimedia Commons API.

Categories:
  bench_anime_01..03  anime-style character illustrations (detailed subjects)
  bench_movie_01..03  public-domain film stills (cinematic composition)
  bench_big_01..02    very large images (6000px+), stress ref preprocessing

These replace the synthetic PIL gradients for ref2v/i2v benchmarking — real
detail levels tax the reference encoder realistically. Re-runnable; skips
files that already exist.
