Owner: codex
Status: In Progress

Reuse the approved Code left rail for conversation programming settings (/project-config?agent=…) and its plugin resource route, including navigation/brand, shared resize/collapse, project rows, footer gallery and account placement.

User explicitly supersedes the old config-specific header/gallery omission. Keep project configuration content, APIs, back/unsaved guards, session/project identities, current home-entry behavior and all trial inherited features unchanged. Renderer-only update preserves actual Main process/bytes. Load the Code skin from shared layout for direct route/reload.

Implemented a shared Code sidebar route scope for /chat, /project-config and descendants. TitleBar uses a sidebar-specific layout flag so configuration title/project context/logo and main content padding retain their existing behavior.
Removed configuration-only suppression of brand/header and gallery footer; project/session/account state and handlers are shared. Moved Code CSS loading to MainLayout so direct configuration entry and reload include the approved skin. Only two CSS scoping rules changed; footer rules and accepted placement remain exact.
README behavior updated; focused Electron and trial update pending.

Official Concurrent/Planning Gates passed; 64 peer records/192 sections inspected read-only, no blocking semantic conflict.
Typecheck, scoped ESLint, default full build:vite passed.
40 focused unit tests passed across layout peek, sidebar project actions, community, module navigation and Canvas layout.
Focused Electron flow and native trial refresh pending.
