feat(art): replace all 72 posts' artwork with the v2 pipeline
Every post now carries one unique local-ComfyUI/Ideogram 4 base frame, composited
into EN + ZH share cards, a banner and list thumbs.

- the shipped prompts_catalog held only 21 distinct metaphors for 72 posts (16
  shared one visual), so all 72 were rewritten as unique object+state metaphors
  and 10 frames re-rolled after OCR found pseudo-text rendered at legible size
- render_from_art.mjs emits JPEG by default (558 KB PNG -> 84 KB mozjpeg q85);
  the ZH 1200x630 card did not exist before this batch
- 288 frontmatter fields migrated; the 144 v1 PNGs are gone
- PostList's thumb helper keys off the base slug (a ZH card is zh-<slug>.jpg while
  the thumb is <slug>-800.webp, which 404'd the whole ZH listing)
- [...slug].astro's <picture> regex accepts .jpg
- the repo now carries the art inputs (metaphors.json, captions/<slug>.json,
  refreshed prompts_catalog.json) so a frame is reproducible from git alone

"""sync_prompts_catalog.py — freeze the art inputs into the repo.
The metaphors and captions are authored in the Ideogram 4 tool dir
(`C:/AI/ideogram4/`), which is NOT in this repository. Without this script the
repository could not reproduce a single frame: `prompts_catalog.json` would still
describe the 21 shared metaphors that produced the near-duplicate v1-adjacent art.
This copies the authoring state into the repo so git alone is enough:
scripts/og-gen/metaphors.json slug -> the unique metaphor (72/72 distinct)
scripts/og-gen/captions/<slug>.json the exact structured caption sent to the model
scripts/og-gen/prompts_catalog.json same shape as before, refreshed from the above
Usage:
python scripts/og-gen/sync_prompts_catalog.py # uses C:/AI/ideogram4
python scripts/og-gen/sync_prompts_catalog.py --tool-dir D:/other
python scripts/og-gen/sync_prompts_catalog.py --check # report only, no writes
