 - **Declare `og:image:width/height` explicitly** — mis-declared dimensions get preview cards rejected by WhatsApp/Telegram/LinkedIn.
 - **Favicon**: reference all sizes (`.ico` + 32×32 + 192×192 PNG + apple-touch 180×180). "Favicon not showing" is usually browser cache, not a missing asset — `curl` the live files before "fixing".

 - Verified with headless Chrome by injecting the built `<section class="related">` + built CSS into a probe at 1264 / 884 / 500 px: `gridTemplateColumns` = 3 / 2 / 2 columns, visible cards 6 / 6 / 4, `scrollWidth == clientWidth` everywhere (no overflow), 6/6 images decoded.
 - ⚠ Headless `--window-size=390` is silently clamped to **500** on Windows — the right-hand column looks clipped in the screenshot, but that is the capture, not the layout. Verify <500px by putting the probe in a 390px `<iframe>` and screenshotting that.
 - ⚠ `--virtual-time-budget` can expire before lazy images paint (5 of 6 cards came out as empty `var(--border)` rectangles at budget 6000). Use ≥20000 before declaring an image broken.
+- **Tag pages now carry the same chrome as `/posts/`** (`/tags/<tag>/` and `/zh/tags/<tag>/` used to pass `chrome={false}` and show only a count line): the title/tag filter input, the category chips and the tag-chip strip. Category chips and the row filter stay scoped to the posts on the page, so their counts match the rows; the tag strip is built from the whole language collection (`chipPosts`) because those chips *navigate* — page-scoped counts there would lie — and the tag being viewed gets `is-active` + `aria-current`. Measured at 1264/500px: gaps 8px/22px between bar → category chips → tag chips → list, `scrollWidth < clientWidth`, 14 tag chips, 4 category chips on /tags/docker/.
 - Bytes: 6 × ~65 KB JPEG ≈ 390 KB, `loading="lazy"` and below the fold. The `/og/thumb/` WebPs (5.8 / 16.1 KB) are keyed by base slug with **no ZH variant**, so they cannot be used here without first emitting `/og/thumb/zh-<slug>-{400,800}.webp`.
 
+### Phase H — Two posts shipped without art (2026-10-20), and the gate that stops it recurring
+- ⚠ **Cause**: the two posts from 2026-10-20 (`yue2-on-a-12gb-gpu-songs-that-lost-their-endings`, `generating-subtitles-for-songs-without-timestamps`, EN+ZH) were published text-complete only. `render_from_art.mjs` **reads** `ogImage`/`banner` but nothing **writes** them, and after the 2026-10-19 bulk migration no script had to — so both pages advertised `/og-default.jpg` (generic card in every share preview and in the new related grid) and rendered no hero banner. The pipeline itself was fine and up to date: `python scripts/og-gen/sync_prompts_catalog.py --check` named exactly these two slugs (`missing=[...]`, 73 metaphors vs 75 posts), which is the check nobody ran before pushing.
+- ✅ Art generated with the current one-command flow (`C:/AI/ideogram4/post_art.py --slug … --metaphor … --evidence …`), same v2 semantic style as the other 73: no-text 1360×768 frame → 1600×900 banner (jpg+webp) → EN card → ZH card → 400/800 thumbs.
+- ✅ **New gate**: `scripts/check-assets.mjs` runs as step 1 of `npm run build`, so a post that is text-complete but not image-complete now fails the Gitea Actions build instead of reaching nginx. It checks, per published post: `ogImage` present and language-correct (EN `/og/<slug>.jpg`, ZH `/og/zh-<slug>.jpg`), `banner` present (`/banners/<slug>.jpg`, shared by both languages), and the existence of banner `.jpg` + `.webp` + `-400` + `-800` thumbs. First run against the unfixed tree reported 16 problems, all on these two slugs and nothing else — it catches this bug class and is silent on the other 73 posts.
+- Frontmatter for the two posts now carries all four fields; nothing else about the posts changed.
+
 ### Phase A — Identity (DONE)
 - ✅ Real headshot in the About hero, the author card on every post, the home hero (EN + ZH) and JSON-LD `Person.image`; no 404 for any derivative.
 - ✅ One branding line ("Full-Stack Developer & DevOps Engineer") aligned across `SITE.title`, meta description, JSON-LD and the homepage hero.

+ * frontmatter fields that *point* at them (`ogImage`, `banner`) are added by
+ * hand — they were bulk-migrated for the first 72 posts and nothing wrote them
+ * for posts added later. Two posts shipped on 2026-10-20 with an empty
+ * `ogImage`, so their pages advertised /og-default.jpg and rendered no hero
+ * banner, and every related-post card showed the generic default. Nothing in
+ * the build noticed. This script is that notice.
+ *
+ * Runs as the first step of `npm run build`, so a post that is text-complete
+ * but not image-complete cannot reach nginx.
+ *
+ * Rules checked per non-draft post:
+ *   - `ogImage` present, language-correct (EN /og/<slug>.jpg, ZH /og/zh-<slug>.jpg)
+ *   - `banner` present (/banners/<slug>.jpg) — the same banner serves both languages

 我试过的每一个 AI 音乐工具，交出来的东西形状都一样：一个音频文件。没有一个会告诉你**每一句是什么时候唱的**。只想听的话没问题，但只要你想把歌词放到屏幕上 —— 卡拉 OK 的那一行、视频字幕、播放器下面的滚动框 —— 就完全不够用。

 YuE2 是一个 30 亿参数的开源音乐模型，能按风格提示词和歌词唱中文。我把它放在自己那台 12GB 显存的 RTX 3060 上用 ComfyUI 本地跑，一次排了 12 首原创歌 —— 结果第一批出来，**每一首的时长都恰好是 240.000 秒**。这个数字不是巧合，而且是个坏消息。
