Measured against the live site and the cron outputs today, not carried over:
- A1 (author photo) and A3 (featured strip) were still ⬜ although both shipped
(B4 and 6e9d58b) — marked done with the evidence, /start-here left as a
deliberate deferral.
- E3 is fully automated: the LinkedIn half was already a daily no_agent cron
(id 35f8985f609a). 5 posts published as of today's 12:30 tick; its silence is
not proof of work, so the output files are the record.
- E6 closed: HSTS waived by the owner ("无视吧"), re-measured still max-age=0.
Do not re-open.
- E1: CF Web Analytics re-measured absent (0 cloudflareinsights hits, one Umami
tag). It is an owner dashboard action — no token here can enable it and CF
injects the beacon itself, so there is no repo change to make.
- B6 now states the real shape of the artwork work: 0 of 72 posts rolled out,
the live site still serves the v1 images, the 3 consultant questions are
unanswered, the rendered OG card is measured at 558 KB PNG vs 84 KB JPEG q85,
and the promised OCR pseudo-text gate does not exist yet.
og-gen — per-post OG image generator
Generates a branded 1200×630 social-share image for a blog post, matching the
site's cobalt-blue #295cff branding, the logo-square.png mark, and the
"terminal / debugging" visual style.
Usage
node scripts/og-gen/generate.mjs <post-slug>
Reads frontmatter (title, category, tags) from
src/content/posts/<slug>.md, fills template.html, renders with headless
Chrome, and writes public/og/<slug>.png.
The post's frontmatter needs ogImage: /og/<slug>.png so the blog serves it
(layout already renders og:image + width/height; PostList shows it as a
card thumbnail).
Customizing the terminal box
Each post shows a "terminal" panel (the red error / green fix lines). Add an
entry keyed by slug in TERMINALS inside generate.mjs, using these tokens:
<div class="line"><span class="prompt">$</span><span class="cmd">command</span></div>
<div class="line"><span class="prompt"> </span><span class="err">error line</span></div>
<div class="line"><span class="prompt">$</span><span class="cmd">fix</span><span class="fix">→ done ✓</span></div>
No entry → a generic default terminal.
Requirements
- Google Chrome at
C:\Program Files\Google\Chrome\Application\chrome.exe(override withCHROME_PATHenv var). - Node 20+.
Notes
- PNG (not JPG) is intentional: for flat UI/terminal art, PNG is smaller and sharper than JPG (see commit history).
- The
logo-square.pngreferenced lives atpublic/logo-square.png.
v2 pipeline ("one art, four targets") — render_from_art.mjs
The consultant-approved redesign replaces the generated terminal panels with one zero-text base-art frame per post, composited into four assets:
| Target | Path | Size |
|---|---|---|
| hero banner | public/banners/<slug>.webp (+ .jpg fallback from frontmatter) |
1600×900 |
| social card | public/og/<slug>.jpg (EN), public/og/zh-<slug>.jpg (ZH) |
1200×630 |
| bento/list thumb | public/og/thumb/<slug>-800.webp |
800×420 |
| small thumb | public/og/thumb/<slug>-400.webp |
400×210 |
The card is template-v2.2.html (frosted bento + blueprint grid + full-width evidence
bar) filled from the post's own frontmatter plus art-meta.json; the self-fitting
headline script reports FIT <n>px through <title>, and a render that does not
settle fails instead of shipping a silently-shrunken card.
# metadata first: art path (default <art-dir>/<slug>.png) + a HAND-WRITTEN evidence line
$EDITOR scripts/og-gen/art-meta.json

--format jpg(default) orpng. JPEG is the default because it is measured: a composited card renders 558 KB as PNG and lands at 84 KB at mozjpeg q85 (256-colour PNG = 240 KB). The default site card already ships as JPG for the same reason.evidenceis required and never derived — it is editorial text, and inventing one from the description is the "invented specificity" failure the blog avoids. A missing entry aborts with the slug list.ogTitle_en/ogTitle_zhshorten only the card's headline (the article keeps its real title) — the consultant's answer to the English headline-rag problem.- Reproducibility check: re-rendering the two sample posts produced banners and 800px thumbs byte-identical to the consultant's accepted delivery (sha256 16e6a7b0…, f3b29f38…, c4e28291…, 8095ec6c…).
