Refactor to multi-category catalog with polished light mode

- Restructure from single filament table to multi-category product catalog
  (filamenti, stampaci, ploce, mlaznice, delovi, oprema)
- Add shared layout components (SiteHeader, SiteFooter, CategoryNav, Breadcrumb)
- Add reusable UI primitives (Badge, Button, Card, Modal, PriceDisplay, EmptyState)
- Add catalog components (CatalogPage, ProductTable, ProductGrid, FilamentCard, ProductCard)
- Add admin dashboard with sidebar navigation and category management
- Add product API endpoints and database migrations
- Add SEO pages (politika-privatnosti, uslovi-koriscenja, robots.txt, sitemap.xml)
- Fix light mode: gradient text contrast, category nav accessibility,
  surface tokens, card shadows, CTA section theming

 ## Project Overview
 
 Filamenteka is a 3D printing filament inventory management system for tracking Bambu Lab filaments. It consists of:
-- **Frontend**: Next.js app with React, TypeScript, and Tailwind CSS (static export)
+- **Frontend**: Next.js app with React, TypeScript, and Tailwind CSS (static export to `/out`)
-- **Backend**: Node.js API server with PostgreSQL database
+- **Backend**: Node.js Express API server (`/api/server.js`) with PostgreSQL database
-- **Infrastructure**: AWS (Amplify for frontend, EC2 for API, RDS for database)

 ## Architecture
 
-### Frontend Structure (Next.js App Router)
+### Frontend (Next.js App Router)
-- `/app` - Next.js 13+ app directory structure
+- `/app/page.tsx` — Public filament inventory table (home page)
-  - `/page.tsx` - Public filament inventory table
+- `/app/upadaj/` — Admin panel: login, `/dashboard` (filament CRUD), `/colors` (color management), `/requests` (customer color requests)
-  - `/upadaj` - Admin panel (password protected)
+- `/src/services/api.ts` — Axios instance with auth interceptors (auto token injection, 401/403 redirect)
-    - `/page.tsx` - Admin login
+- `/src/data/bambuLabColors.ts` — Primary color-to-hex mapping with gradient support (used by `ColorCell` component)
-    - `/dashboard/page.tsx` - Filament CRUD operations
+- `/src/data/bambuLabColorsComplete.ts` — Extended color database grouped by finish type (used by filters)
-    - `/colors/page.tsx` - Color management
 
-### API Structure
+### API (`/api/server.js`)
-- `/api` - Node.js Express server (runs on EC2)
+Single-file Express server running on EC2 (port 80). All routes inline.
-  - `/server.js` - Main server file
+- Endpoints: `/api/login`, `/api/filaments`, `/api/colors`, `/api/sale/bulk`, `/api/color-requests`
-  - `/routes` - API endpoints for filaments, colors, auth
+- Auth: JWT tokens with 24h expiry, single admin user (password from `ADMIN_PASSWORD` env var)
-  - Database: PostgreSQL on AWS RDS
 
-### Key Components
+### Database (PostgreSQL on RDS)
-- `FilamentTableV2` - Main inventory display with sorting/filtering
+Key schemas and constraints:
-- `SaleManager` - Bulk sale management interface
-- `ColorCell` - Smart color rendering with gradient support
-- `EnhancedFilters` - Advanced filtering system
 
-### Data Models
+```
-
+filaments: id, tip (material), finish, boja (color), refill, spulna, kolicina, cena, sale_*
-#### Filament Schema (PostgreSQL)
+colors: id, name, hex, cena_refill (default 3499), cena_spulna (default 3999)
-```sql
+color_requests: id, color_name, message, contact_name, contact_phone, status
-filaments: {
-  id: UUID,
-  tip: VARCHAR(50),        # Material type (PLA, PETG, ABS)
-  finish: VARCHAR(50),     # Finish type (Basic, Matte, Silk)
-  boja: VARCHAR(100),      # Color name
-  refill: INTEGER,         # Refill spool count
-  spulna: INTEGER,         # Regular spool count
-  kolicina: INTEGER,       # Total quantity (refill + spulna)
-  cena: VARCHAR(50),       # Price
-  sale_active: BOOLEAN,    # Sale status
-  sale_percentage: INTEGER,# Sale discount
-  sale_end_date: TIMESTAMP # Sale expiry
-}
 ```
 
-#### Color Schema
+**Critical constraints:**
-```sql
+- `filaments.boja` → FK to `colors.name` (ON UPDATE CASCADE) — colors must exist before filaments reference them
-colors: {
+- `kolicina = refill + spulna` — enforced by check constraint
-  id: UUID,
+- Migrations in `/database/migrations/` with sequential numbering (currently up to `020_`)
-  name: VARCHAR(100),      # Color name (must match filament.boja)
-  hex: VARCHAR(7),         # Hex color code
-  cena_refill: INTEGER,    # Refill price (default: 3499)
-  cena_spulna: INTEGER     # Regular price (default: 3999)
-}
-```
 
-## Deployment
+## Key Patterns
 
-### Frontend (AWS Amplify)
+### Color Management (two-layer system)
-- Automatic deployment on push to main branch
+1. **Database `colors` table**: Defines valid color names + pricing. Must be populated first due to FK constraint.
-- Build output: Static files in `/out` directory
+2. **Frontend `bambuLabColors.ts`**: Maps color names → hex codes for UI display. Supports solid (`hex: '#FF0000'`) and gradient (`hex: ['#HEX1', '#HEX2'], isGradient: true`).
-- Config: `amplify.yml`, `next.config.js` (output: 'export')
+3. Color names must match exactly between `colors.name`, `filaments.boja`, and `bambuLabColors.ts` keys.
+4. The `ColorCell` component renders table row backgrounds from these mappings.
 
-### API Server (EC2)
+### Adding New Colors
-- Manual deployment via `scripts/deploy-api.sh`
+1. Add to database `colors` table (via admin panel at `/upadaj/colors` or migration)
-- Server: `3.71.161.51`
+2. Add hex mapping to `src/data/bambuLabColors.ts`
-- Domain: `api.filamenteka.rs`
+3. Optionally add to `src/data/bambuLabColorsComplete.ts` finish groups
-
-### Database (RDS PostgreSQL)
-- Host: `filamenteka.ci7fsdlbzmag.eu-central-1.rds.amazonaws.com`
-- Migrations in `/database/migrations/`
-- Schema in `/database/schema.sql`
-
-## Important Patterns
 
 ### API Communication
-- All API calls use axios interceptors for auth (`src/services/api.ts`)
+- Service modules in `src/services/api.ts`: `authService`, `colorService`, `filamentService`, `colorRequestService`
-- Auth token stored in localStorage
+- Auth token stored in localStorage with 24h expiry
-- Automatic redirect on 401/403 in admin routes
+- Cache busting on filament fetches via timestamp query param
 
-### Color Management
+## CI/CD (Gitea Actions)
-- Colors defined in `src/data/bambuLabColors.ts` and `bambuLabColorsComplete.ts`
-- Automatic row coloring based on filament color
-- Special handling for gradient filaments
 
-### State Management
+`.gitea/workflows/deploy.yml` triggers on push to `main`. Auto-detects changes via `git diff HEAD~1`:
-- React hooks for local state
+- **Frontend changes** (anything outside `api/`): security check → tests → build → S3 deploy (3-tier cache: HTML no-cache, `_next/` immutable, rest 24h) → CloudFront invalidation
-- No global state management library
+- **API changes** (`api/` files): SSM command to EC2 to pull `server.js` from Gitea and restart `node-api` service
-- Data fetching in components with useEffect
+- Both run if both changed in a single push
 
-### Testing
+## Deployment Details
-- Jest + React Testing Library
+
-- Tests in `__tests__/` directory
+| Component | Target | Method |
-- Coverage goal: >80%
+|-----------|--------|--------|
+| Frontend | S3 `filamenteka-frontend` → CloudFront | Static export, OAC-protected |
+| API | EC2 `i-03956ecf32292d7d9` | SSM, systemd `node-api` service |
+| Database | RDS `filamenteka.ci7fsdlbzmag.eu-central-1.rds.amazonaws.com` | Migrations via `scripts/update-db-via-aws.sh` |
+| DNS | Cloudflare | `api.filamenteka.rs` → EC2 |

 ```
 
-## Security Considerations
+## Pre-commit Hooks (Husky)
 
-- Admin routes protected by JWT authentication
+`scripts/pre-commit.sh` runs automatically and blocks commits that fail:
-- Password hashing with bcrypt
+1. Author mention check (blocks attribution)
-- SQL injection prevention via parameterized queries
+2. Security check (credential leaks)
-- Credential leak detection in pre-commit hooks
+3. Build test (ensures compilation)
-- CORS configured for production domains only
+4. Unit tests (`jest --passWithNoTests`)
-
-## Database Operations
-
-When modifying the database:
-1. Create migration file in `/database/migrations/`
-2. Test locally first
-3. Run migration on production via scripts
-4. Update corresponding TypeScript types
-
-## Terraform Infrastructure
-
-Infrastructure as Code in `/terraform/`:
-- VPC and networking setup
-- EC2 instance for API
-- RDS PostgreSQL database
-- Application Load Balancer
-- ECR for Docker images
-- Cloudflare DNS integration
