Deploy / build (push) Successful in 17s
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

"""migrate_to_v2_assets.py — point the content at the v2 artwork filenames.
|
|
|
|
The v2 renderer (render_from_art.mjs) writes JPEG/WebP, not PNG:
|
|
public/banners/<slug>.jpg (hero fallback; <picture> derives .webp)
|
|
public/og/<slug>.jpg (EN share card)
|
|
public/og/zh-<slug>.jpg (ZH share card)
|
|
|
|
Until this migration runs, every page still points at the v1 PNG paths, so it has
|
|
to happen in the SAME commit as the images or the site serves 404 heroes.
|
|
|
|
Idempotent: it only rewrites values that still look like the v1 paths, keeps each
|
|
file's quoting style, and prints what it changed. Run with --write to apply.
