# Project: Грибы Крыма — Encyclopedia & Calendar

## Tech Stack
- Next.js 15 (App Router), TypeScript strict, Tailwind CSS 4, React 19
- Static data (JSON) — no backend/database needed
- Deploy target: static export or Node.js server

## Architecture
- `src/app/` — pages (App Router)
- `src/components/` — reusable UI components
- `src/data/` — mushroom database (JSON/TS)
- `src/lib/` — utilities, helpers, types
- `public/images/` — mushroom photos

## Coding Standards
- Functional components only, prefer named exports
- Use `interface` for props, `type` for unions/intersections
- All components must be typed — no `any`
- Russian UI text, English code identifiers
- Use semantic HTML elements
- Mobile-first responsive design
