+# ChicoryTV SPA App Shell Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the ChicoryTV React admin shell for Gitea issue #82: fixed sidebar, compact top bar, client-side screen slots, Connect menu, and mounted theme switcher.
+
+**Architecture:** Keep the shell in `web/src/App.tsx` because the current SPA is still small and the issue is about top-level chrome. Use local React state plus `history.pushState`/`popstate` for lightweight client-side routing without adding dependencies. Keep styling in the existing `web/src/shell.css` stub and reuse the ported design-system primitives.
+
+**Tech Stack:** React 19, TypeScript, Vite, Vitest, Testing Library, Lucide React, ChicoryTV design-system CSS tokens.
+
+---
+
+### Task 1: Shell Behavior Tests
+
+**Files:**
+- Modify: `web/src/App.test.tsx`
+
+- [ ] **Step 1: Replace scaffold expectations with shell expectations**
+
+Add tests that render `App`, assert the 232px sidebar/top-bar shell content is present, verify navigation moves between placeholder screens, verify the Connect menu exposes M3U/XMLTV endpoints, and keep the existing theme persistence coverage.
+
+- [ ] **Step 2: Run tests to verify failure**
+
+Run: `cd web && npm test -- --run src/App.test.tsx`
+
+Expected: tests fail because the current scaffold still renders "SPA foundation ready" and does not implement routed placeholder screens or the Connect menu.
+
+### Task 2: App Shell Implementation
+
+**Files:**
+- Modify: `web/src/App.tsx`
+- Modify: `web/src/shell.css`
+
+- [ ] **Step 1: Implement shell structure**
+
+Replace the scaffold/gallery with:
+- Sidebar brand row, primary/media/system nav, health footer.
+- Top bar with page title, search input, Connect menu, help/notification/avatar controls, and per-screen primary action slot.
+- Theme switcher mounted in the shell.
+- Placeholder content for Dashboard, Channels, New Channel, Guide, Schedules, Playouts, Collections, Libraries, and Settings.
+
+- [ ] **Step 2: Implement routing**
+
+Use a route table with paths under `/app`, `window.location.pathname`, `history.pushState`, and `popstate` to update active nav and rendered screen without a full reload.
+
+- [ ] **Step 3: Style to prototype**
+
+Rewrite `shell.css` so the sidebar is 232px, top bar is 52px, active nav uses accent rail plus soft tint, content scrolls independently, and the layout remains usable on narrow screens.
+
+- [ ] **Step 4: Run focused tests**
+
+Run: `cd web && npm test -- --run src/App.test.tsx`
+
+Expected: all `App` tests pass.
+
+### Task 3: Verification
+
+**Files:**
+- No code changes expected.
+
+- [ ] **Step 1: Run web test suite**
+
+Run: `cd web && npm test -- --run`
+
+Expected: all tests pass.
+
+- [ ] **Step 2: Run lint**
+
+Run: `cd web && npm run lint`
+
+Expected: no lint errors.
+
+- [ ] **Step 3: Run production build**
+
+Run: `cd web && npm run build`
+
+Expected: TypeScript and Vite build successfully.
