+# Papr Styles & Architecture Analysis
+
+## Overview
+
+Papr is a minimalistic document management and archiving platform that serves as an excellent reference for building Trackeep. This analysis examines their architectural patterns, technology choices, and design principles that can inform our development approach.
+
+## Technology Stack Analysis
+
+### Frontend Architecture
+
+**Core Technologies:**

+- **Shadcn Solid** - UI component library based on Shadcn designs
+- **UnoCSS** - Atomic CSS engine for instant styling
+- **Tabler Icons** - Minimalist icon set
+- **Vite** - Build tool and dev server
+
+**Key Dependencies:**
+```json
+{
+  "solid-js": "^1.9.9",
+  "@kobalte/core": "^0.13.10", // Accessible components
+  "@modular-forms/solid": "^0.25.1", // Form handling
+  "@solidjs/router": "^0.14.10", // Routing
+  "@tanstack/solid-query": "^5.90.3", // Data fetching
+  "@tanstack/solid-table": "^8.21.3", // Table components
+  "class-variance-authority": "^0.7.1", // Component variants
+  "tailwind-merge": "^2.6.0", // Class merging
+  "valibot": "catalog:" // Schema validation
+}
+```
+
+### Backend Architecture
+
+**Core Technologies:**
+- **HonoJS** - Lightweight, fast web framework
+- **Drizzle ORM** - Type-safe database operations
+- **Better Auth** - Authentication solution
+- **CadenceMQ** - Self-hosted job queue (built by Papr team)
+- **LibSQL/Turso** - Database solution
+
+**Key Dependencies:**
+```json
+{
+  "hono": "^4.10.7",
+  "drizzle-orm": "^0.38.4",
+  "better-auth": "catalog:",
+  "@cadence-mq/core": "^0.2.1",
+  "@libsql/client": "^0.14.0",
+  "zod": "^3.25.67" // Schema validation
+}
+```
+
+## Architectural Patterns
+
+### 1. Monorepo Structure
+```
+papra/
+├── apps/
+│   ├── papra-client/     # Frontend application
+│   ├── papra-server/     # Backend API
+│   └── lecture/          # Documentation
+├── packages/
+│   ├── search-parser/    # Shared utilities
+│   └── webhooks/         # Webhook handling
+└── docs/                 # Documentation site
+```
+
+### 2. Workspace Management
+- Uses **PNPM Workspaces** for monorepo management
+- Shared packages with `workspace:*` dependencies
+- Catalog system for managing version consistency
+
+### 3. Development Workflow
+- **TypeScript** throughout for type safety
+- **ESLint** with `@antfu/eslint-config` for code quality
+- **Vitest** for testing framework
+- **GitHub Actions** for CI/CD
+
+## Design Patterns & Principles
+
+### 1. Component Architecture
+- **Shadcn-inspired** component system
+- **Class Variance Authority (CVA)** for component variants
+- **Tailwind-merge** for class name optimization
+- **Accessibility-first** with Kobalte components
+
+### 2. State Management
+- **SolidJS signals** for reactive state
+- **TanStack Query** for server state management
+- **Local storage** integration with `@solid-primitives/storage`
+
+### 3. Styling Strategy
+- **Atomic CSS** with UnoCSS
+- **Utility-first** approach
+- **Dark mode** as primary theme
+- **Minimalistic design** inspired by modern document management tools
+
+### 4. API Design
+- **RESTful** patterns with Hono
+- **Type-safe** routes with TypeScript
+- **Authentication** integrated throughout
+- **File upload** handling with busboy
+
+## Key Features Implementation
+
+### 1. Document Management
+```typescript
+// File upload handling
+- busboy for multipart uploads
+- AWS S3/Azure Blob storage integration
+- Local file system support
+- MIME type detection
+```
+
+### 2. Search Functionality
+```typescript
+// Search parser package
+- Custom query language
+- Full-text search capabilities
+- Tag-based filtering
+- Content extraction from documents
+```
+
+### 3. Authentication
+```typescript
+// Better Auth integration
+- Email/password authentication
+- OAuth providers
+- Session management
+- API key authentication
+```
+
+### 4. Background Jobs
+```typescript
+// CadenceMQ integration
+- Document processing
+- Email ingestion
+- Content extraction
+- Automated tagging
+```
+
+## Deployment & Infrastructure
+
+### 1. Container Strategy
+- **Docker** image < 200MB
+- **Multi-architecture** support (x86, ARM64, ARMv7)
+- **Single command** deployment
+
+### 2. Hosting Solutions
+- **Cloudflare Pages** for static assets
+- **Fly.io** for backend hosting
+- **Turso** for production database
+
+### 3. Self-Hosting Focus
+- **Docker Compose** ready
+- **Environment variable** configuration
+- **SQLite** for lightweight deployments
+- **Migration system** for database updates
+
+## Code Quality Standards
+
+### 1. TypeScript Configuration
+- Strict mode enabled
+- Path mapping for clean imports
+- Consistent linting rules
+- Automated type checking
+
+### 2. Testing Strategy
+- **Unit tests** with Vitest
+- **Integration tests** with testcontainers
+- **Coverage reporting** with v8
+- **Watch mode** for development
+
+### 3. Build Process
+- **ESBuild** for fast bundling
+- **Tree shaking** for optimization
+- **Minification** for production
+- **Source maps** for debugging
+
+## Performance Optimizations
+
+### 1. Frontend Optimizations
+- **SolidJS** fine-grained reactivity
+- **Code splitting** with lazy loading
+- **Image optimization** and lazy loading
+- **Service worker** for caching
+
+### 2. Backend Optimizations
+- **Connection pooling** for database
+- **Async processing** with job queues
+- **File streaming** for large uploads
+- **Caching layers** for frequent queries
+
+### 3. Database Optimizations
+- **Index optimization** for search
+- **Connection management** with Drizzle
+- **Migration system** for schema updates
+- **Backup strategies** for data safety
+
+## Security Considerations
+
+### 1. Authentication & Authorization
+- **JWT tokens** for API access
+- **Session management** with secure cookies
+- **Role-based access control**
+- **API rate limiting**
+
+### 2. Data Protection
+- **Input validation** with Zod
+- **SQL injection prevention** with ORM

+
+### 3. Privacy Features
+- **End-to-end encryption** option
+- **Data anonymization** capabilities
+- **GDPR compliance** features
+- **User data export** functionality
+
+## Lessons for Trackeep Development
+
+### 1. Technology Choices
+- **SolidJS** over React for better performance
+- **Hono** instead of Express for lightweight API
+- **Drizzle** over Prisma for better TypeScript support
+- **UnoCSS** over Tailwind for atomic CSS benefits
+
+### 2. Architecture Decisions
+- **Monorepo** structure for better code sharing

+> **Tagline:** "Track, save, and organize everything that matters to you."
+
+## Project Overview
+
+Trackeep is an open-source, self-hosted platform designed to help you store, organize, and track all your digital content—from bookmarks and documents to learning progress, tasks, media, and files. Think of it as a hybrid of Papr, Notion, Pocket, and Todo apps, built for developers, learners, and knowledge workers who want full control over their data.

+## Overview
+
+Trackeep provides a RESTful API for managing bookmarks, tasks, files, and notes. All API endpoints (except authentication) require a valid JWT token.
+
+**Base URL:** `http://localhost:8080/api/v1`
+
+**Authentication:** Bearer Token (JWT)
+
+## Authentication
+
+### Register User
+```http
+POST /auth/register
+Content-Type: application/json
+
+{
+  "email": "user@example.com",
+  "password": "password123",
+  "name": "John Doe"
+}
+```
+
+**Response:**
+```json
+{
+  "message": "User created successfully",
