   - **Desktop banner height** capped (720px, centred): 67% → **45%** of a 900px viewport, art intact rather than cropped.
   - Measured post page: images **277 KB → 38 KB**, height **5,758 → 5,065px** desktop / 9,423 → 8,807px mobile. Script: `scripts/optimize-images.py`; format policy: `design-guide.md` §3; runbook step in `ops-runbook.md`.
 
+- ✅ **B7 review-response batch, 2026-10-19** — an outside content/UX review of the live site was reconciled claim-by-claim against the repo; only the measured defects were acted on.
+  - **About counter was hand-typed and had drifted**: `about.astro` said **71** write-ups while the homepage rendered **72**. Both About pages now count from the collection (`getCollection('posts', isEn|isZh).length`), so the number cannot drift again.
+  - **Reading time was English-only maths**: `minutesOf` split the body on whitespace and divided by 200, so a Chinese post (no interior spaces) showed **1 min** against **5 min** for its English twin. New `src/lib/reading-time.ts` counts CJK ideographs at ~400/min plus Latin words at 200/min; pure-ASCII bodies are unchanged (same formula), the ZH post now reads **5 分钟**, and the ZH article header no longer says "min read".
+  - **ZH copy defects**: `主陆开发者` → `中国大陆开发者`; `基元律动值得麻烦的原因` → `为什么值得考虑基元律动` (the English twin already said *why it is worth the hassle*).
+  - **`hello-world` contradicted the site**: it still declared English primary with selective Chinese, and quoted a `~140-container homelab`. Both language twins now say every post exists in both languages and quote **162 containers across three self-managed hosts**.
+  - **`0 hosting companies between me and the servers` was loose** (the VPS is rented from a provider) → `0 managed hosting layers — I run all three hosts myself` (EN + ZH).
+  - **Hero sub-paragraph now leads with the capability**, not the container count; the number follows as evidence. `<h1>` and `title`/JSON-LD were left alone (A2 identity alignment).
+  - **Featured bento cards got the `srcset`/`sizes` they were missing** (`-400`/`-800` webp) — they were downloading the 800px file for a 226–341px slot. At DPR1 all widths now pick `-400`; card geometry measured unchanged (226/227/310/341 px).
+  - **Measured, not assumed**: 12 routes × 4 widths (360/390/414/768) = **48/48 with zero horizontal overflow** (`scrollWidth − clientWidth == 0`); art uniformity re-surveyed — 72/72 banners 1600×900 WebP, 72/72 `-800` thumbs 800×420, 72/72 `-400` thumbs 400×210, 144/144 share cards 1200×630 JPEG. Build **251 pages**, unchanged.
+  - Deliberately **not** done, because the review's premise was stale or wrong: `hreflang`/canonical/`og:locale` and per-post OG images already ship (72/72 + 72/72), and the art system was already unified by B6b (round 7) — the reviewer was reading screenshots from before that rollout for the *visual* half.
