 - ✅ **B5 baseline & hygiene** (2026-10-18, `3f63150`) — `/og-default.jpg` 211 KB → 45 KB carrying the headshot; banner-404 sweep to 72/72 clean; CJK system font stack; A2 branding alignment.
 - ✅ **B6 visual redesign + Ideogram 4 pipeline** (2026-10-18) — the consultant's hybrid "one art, four targets" template; bento theme tokens (a hardcoded dark scrim measured 1.96:1 text contrast in the light theme → 6.10). Phase F is its rollout.
 - ✅ **B7 review-response** (2026-10-19, `5941e85` + `5ec321a`) — About counter derived from the collection (71 → **72**); reading time is CJK-aware (ZH **1 min → 5 分钟**); ZH wording fixes; `hello-world`'s stale language policy and container count; hero leads with the capability; featured cards got the `srcset` they lacked; **48/48** mobile-overflow combinations at 0 px.

+  - Stream separation: Homepage splits into 6 engineering posts + bottom GPU & Multimodal Lab strip.
+  - Top navigation: `Blueprints | Case Studies | All Posts | Work With Me` (ZH: `系统蓝图 | 工程案例 | 全部文章 | 关于与合作`).
+  - Hero CTA: Malaysian SME button anchors directly to `/about/#sme` (ZH: `/zh/about/#sme`).
+  - Dual-track `/about/` retains canonical URL, redirects `/work-with-me/` via 301.
+  - Three System Blueprints (`/blueprints/` and `/zh/blueprints/`):
+    - `self-hosted-infrastructure` (162 Containers, 4 Layers)
+    - `ai-agent-automation` (Deterministic Workflows + GPU Inference, 4 Layers)
+    - `sme-digital-suite` (High-Performance Web, SifuMail, Entitlements, 4 Layers)
+  - 94 post files mounted to the 12 Blueprint Layers across EN and ZH with in-article breadcrumbs.
+  - Schema.org `TechArticle` enrichment with `dependencies` and `audience`.
