chore: D22 落地——docs/SDD/wiki/CLAUDE.md 進 repo（Gitea private 預設全 push）

頂層 D22 決策（leo 2026-07-03 拍板）：推什麼由開發環境歸屬決定，
Gitea private＝除機敏值/build 產物/.github 外全 push。
解 T1.5 卡點：雲端工人 clone 拿得到 credential-store-migration.md，可就地改寫 SDD。
機敏掃描兩輪通過（新增 189 檔約 2.1MB，node_modules/dist/wasm 照舊排除）。

+# CODING AGENTS: READ THIS FIRST
+
+This is a **handoff bundle** from Claude Design (claude.ai/design).
+
+A user mocked up designs in HTML/CSS/JS using an AI design tool, then exported this bundle so a coding agent can implement the designs for real.
+
+## What you should do — IMPORTANT
+
+**Read the chat transcripts first.** There are 1 chat transcript(s) in `arcrun/chats/`. The transcripts show the full back-and-forth between the user and the design assistant — they tell you **what the user actually wants** and **where they landed** after iterating. Don't skip them. The final HTML files are the output, but the chat is where the intent lives.
+
+**Find the primary design file under `arcrun/project/` and read it top to bottom.** The chat transcripts will tell you which file the user was last iterating on. Then **follow its imports**: open every file it pulls in (shared components, CSS, scripts) so you understand how the pieces fit together before you start implementing.
+
+**If anything is ambiguous, ask the user to confirm before you start implementing.** It's much cheaper to clarify scope up front than to build the wrong thing.
+
+## About the design files
+
+The design medium is **HTML/CSS/JS** — these are prototypes, not production code. Your job is to **recreate them pixel-perfectly** in whatever technology makes sense for the target codebase (React, Vue, native, whatever fits). Match the visual output; don't copy the prototype's internal structure unless it happens to fit.
+
+**Don't render these files in a browser or take screenshots unless the user asks you to.** Everything you need — dimensions, colors, layout rules — is spelled out in the source. Read the HTML and CSS directly; a screenshot won't tell you anything they don't.
