 ## Project Overview
 
-Remanso is a Vue 3 + TypeScript web app that displays markdown notes from GitHub repositories with Zettelkasten-style backlinks. Users access notes via `https://remanso.space/{user}/{repo}`. Supports both public repos (direct access) and private repos (GitHub OAuth).
+Remanso is a Vue 3 + TypeScript web app that displays markdown notes from GitHub repositories with Zettelkasten-style backlinks. Users access notes via `https://remanso.space/{user}/{repo}`. Also supports decentralized public notes via ATProto (Bluesky) at `/notes/:did/:rkey`. Supports both public repos (direct access) and private repos (GitHub OAuth).
 
 ## Commands
 
 ```bash
 pnpm dev          # Start development server
 pnpm build        # Production build
-pnpm test         # Run Vitest tests
+pnpm test         # Run Vitest tests (no config file, uses defaults)
 pnpm lint         # ESLint with auto-fix
 pnpm types        # TypeScript type-check
 ```
 
+Run a single test file: `pnpm test src/modules/repo/services/resolvePath.spec.ts`

 ## Architecture
 
 ### Tech Stack
 
-- **Vue 3** with Composition API, **Pinia** for state, **Vue Router**
-- **Vite** build tool, **TypeScript** strict mode
-- **Tailwind CSS** + **DaisyUI** for styling
+- **Vue 3** (3.5) with Composition API, **Pinia** for state, **Vue Router**
+- **Vite 7** build tool, **TypeScript** strict mode
+- **Tailwind CSS v4** + **DaisyUI v5** for styling (PostCSS plugin approach, not tailwind.config.js)
+- **TanStack Vue Query** + **ts-rest** + **arktype** for typed API contracts
 - **PouchDB** (IndexedDB) for local persistence
 - **Octokit** for GitHub API integration
 - **markdown-it** with plugins (KaTeX, Shikiji, Mermaid, checkboxes, GitHub alerts)
 
+### Styling
+
+Tailwind v4 uses the modern CSS-based config in `src/styles/app.css`:
+- `@import "tailwindcss"` instead of directives
+- DaisyUI configured via `@plugin 'daisyui' { themes: retro --default, coffee --prefersdark; }`
+- `@tailwindcss/typography` for prose styling

+### Key Routes
+
+- `/` - Home
+- `/:user/:repo` - Main note view (FluxNoteView) with stacked notes
+- `/:user/:repo/inbox|draft|todo|history` - Specialized note views
+- `/notes` - Public note list (ATProto-based)
+- `/notes/:did/:rkey` - Single public note view
+
 ### Key Files
 
-- `src/router/router.ts` - Route definitions, main route is `/:user/:repo`
+- `src/router/router.ts` - Route definitions
 - `src/modules/repo/store/userRepo.store.ts` - Central Pinia store for repo/file state
 - `src/modules/repo/services/octo.ts` - Octokit wrapper for GitHub API
 - `src/hooks/useMarkdown.hook.ts` - Markdown rendering with all plugins
+- `src/modules/post/data/client.ts` - ts-rest API contract definitions with arktype validation
 - `src/data/data.ts` - PouchDB database wrapper
 
 ### Patterns
 
-- All components use Composition API
+- All components use Composition API (`<script setup lang="ts">`)
 - Custom hooks encapsulate feature logic (`use*.hook.ts` or `use*.ts`)
 - Event buses (`noteEventBus`, `backlinkEventBus`) for cross-component communication
+- ts-rest contracts use arktype schemas for request/response validation
 - Path alias: `@` maps to `src/`
