+# openElement Desktop Reader
+
+Alpha.5 dogfood app proving SPA mode, @openelement/ui custom elements, Preact islands, and third-party web component interop in a Deno Desktop native window.
+
+## Setup
+
+```sh
+deno upgrade canary    # deno desktop requires canary
+```
+
+## Dev
+
+```sh
+deno task dev          # Vite HMR at http://localhost:5173
+```
+
+## Build Desktop
+
+```sh
+deno task build        # Vite build + deno desktop compile
+open deno-desktop-reader.app
+```
+
+## Architecture
+
+- `reader.tsx` — Vite client entry, SPA bootstrap
+- `main.ts` — Deno.serve HTTP server + API + GitHub sync
+- `routes/` — 6 routes (bookshelf, reading, notes, search, settings, wc-interop)
+- `islands/` — Preact island (reader-counter)
+- `components/` — Shared components (BookCard)
+- `app/` — Persistence layer (storage, repo, search, export)
+- `vite.config.ts` — openElement({ mode: 'spa' })
+
+## Validation
+
+This app validates:
+- `@openelement/app/spa` — SPA mode bootstrap
+- `@openelement/ui` — Custom element components
+- `@openelement/core` — JSX runtime
+- Preact islands — `definePreactIsland`
+- Third-party CE — Lit, Shoelace, MWC
