Claude 99d0d1dba1 chore: Add CLAUDE.md, TODO.md, and fix ReadBooks Tailwind classes

- Add CLAUDE.md with project architecture, conventions, and common tasks
- Add TODO.md with prioritized roadmap (book reviews, CMS, n8n, frontend)
- Fix invalid Tailwind classes in ReadBooks.tsx (h-30 -> h-[7.5rem], w-22 -> w-24)

CLAUDE.md - Portfolio Project Guide

Project Overview

Personal portfolio website for Dennis Konkol (dk0.dev). Built with Next.js 15 (App Router), TypeScript, Tailwind CSS, and Framer Motion. Uses a "liquid" design system with soft gradient colors and glassmorphism effects.

Tech Stack

Framework: Next.js 15 (App Router), TypeScript 5.9
Styling: Tailwind CSS 3.4 with custom liquid-* color tokens
Animations: Framer Motion 12
3D: Three.js + React Three Fiber (shader gradient background)
Database: PostgreSQL via Prisma ORM
Cache: Redis (optional)
CMS: Directus (self-hosted, REST/GraphQL, optional)
Automation: n8n webhooks (status, chat, hardcover, image generation)
i18n: next-intl (EN + DE), message files in messages/
Monitoring: Sentry
Deployment: Docker + Nginx, CI via Gitea Actions

Commands

npm run dev          # Full dev environment (Docker + Next.js)
npm run dev:simple   # Next.js only (no Docker)
npm run dev:next     # Plain Next.js dev server
npm run build        # Production build
npm run lint         # ESLint
npm run test         # Jest unit tests
npm run test:e2e     # Playwright E2E tests

Architecture Patterns

Data Source Hierarchy (Fallback Chain)

Directus CMS (if configured via DIRECTUS_STATIC_TOKEN)
PostgreSQL (for projects, analytics)
JSON files (messages/*.json)
Hardcoded defaults
Display key itself as last resort

All external data sources fail gracefully - the site never crashes if Directus, PostgreSQL, n8n, or Redis are unavailable.

CMS Integration (Directus)

REST/GraphQL calls via lib/directus.ts (no Directus SDK)
Collections: tech_stack_categories, tech_stack_items, hobbies, content_pages, projects, book_reviews
Translations use Directus native translation system (M2O to languages)
Locale mapping: en -> en-US, de -> de-DE

n8n Integration

Webhook base URL: N8N_WEBHOOK_URL env var
Auth via N8N_SECRET_TOKEN and/or N8N_API_KEY headers
All n8n endpoints have rate limiting and timeout protection (10s)
Hardcover data cached for 5 minutes

Component Patterns

Client components with "use client" for interactive/data-fetching parts
useEffect for data loading on mount
useTranslations from next-intl for i18n
Framer Motion variants pattern with staggerContainer + fadeInUp
Gradient cards with liquid-* color tokens and backdrop-blur-sm

Design System

Custom Tailwind colors prefixed with liquid-:

liquid-sky, liquid-mint, liquid-lavender, liquid-pink
liquid-rose, liquid-peach, liquid-coral, liquid-teal, liquid-lime

Cards use gradient backgrounds (bg-gradient-to-br from-liquid-*/15 via-liquid-*/10 to-liquid-*/15) with border-2 and rounded-xl.

# Required for n8n features
N8N_WEBHOOK_URL=https://n8n.dk0.dev

N8N_API_KEY=...

# Database

Conventions

Language: Code in English, user-facing text via i18n (EN + DE)
Commit messages: Conventional Commits (feat:, fix:, chore:)
Components: PascalCase files in app/components/
API routes: kebab-case directories in app/api/
CMS data always has a static fallback - never rely solely on Directus
Error logging: Only in development mode (process.env.NODE_ENV === "development")
No emojis in code unless explicitly requested

Common Tasks

Adding a new CMS-managed section

Define the GraphQL query + types in lib/directus.ts
Create an API route in app/api/<name>/route.ts
Create a component in app/components/<Name>.tsx
Add i18n keys to messages/en.json and messages/de.json
Integrate into the parent component (usually About.tsx)

Adding i18n strings

Add keys to messages/en.json and messages/de.json
Access via useTranslations("key.path") in client components
Or getTranslations("key.path") in server components

Working with Directus collections

All queries go through directusRequest() in lib/directus.ts
Uses GraphQL endpoint (/graphql)
2-second timeout, graceful null fallback
Translations filtered by languages_code.code matching Directus locale
