# Project Rules
## Overview
E-commerce platform built with Go microservices and React frontend.
All services communicate via gRPC with Protocol Buffers.
## Go Services
- Follow standard Go project layout (cmd/, internal/, pkg/)
- Use structured logging with slog (not log or fmt.Println)
- Error handling: always wrap errors with fmt.Errorf("%w", err)
- Database access through repository pattern in internal/repo/
- All public functions must have godoc comments
## API Design
- Proto files live in proto/ directory with buf for linting
- Use field masks for partial updates
- Pagination via cursor-based tokens, not offset
## Testing
- Table-driven tests for all business logic
- Use testcontainers-go for integration tests
- Minimum 80% coverage on internal/ packages
- Mock external services with gomock interfaces
## Do Not
- Use global variables or init() functions
- Import internal packages across service boundaries
- Commit generated .pb.go files (CI generates them)

# Project Instructions
## Stack
- React 19 with TypeScript
- Supabase for backend (auth, database, storage)
- TailwindCSS v4 + shadcn/ui components
- Vite for building
## Architecture
- Feature-based folder structure
- Each feature owns its components, hooks, and types
- Shared components in src/components/ui/
- All API calls go through src/lib/supabase.ts
## Conventions
- Use shadcn/ui components before creating custom ones
- Mobile-first responsive design
- Use Supabase RLS policies for authorization
- Prefer server-side filtering over client-side
## Brand
- Primary color: #6366F1 (indigo)
- Font: Inter for body, Cal Sans for headings
- Rounded corners (radius-lg) on all cards
