Features added to project-mode.html:
- Logo upload section in 'Dati Azienda' (matches shop-mode design)
- Base64 logo encoding and preview
- K-means color palette extraction (5-7 colors)
- Average color calculation as brand color
- Visual palette display with color chips
Functions copied from shop-mode:
- handleLogoUpload() - File upload with size validation (2MB max)
- extractDominantColor() - K-means clustering algorithm
- kMeansClustering() - Palette extraction with convergence
- rgbToHex() / hexToRgb() - Color conversion utilities
PDF improvements:
- generaPDFCliente() now includes logo in header
- generaPDFInterno() now includes logo in header
- Dynamic brand colors from extracted palette
- Responsive layout (centered without logo, left-aligned with logo)
- White card background for logo with subtle border
Data persistence:
- logoColor and colorPalette added to salvaDati()
- Logo and palette restored in caricaPreventivoSalvato()
UI features:
- Drag & drop logo upload
- Real-time color extraction on upload
- Palette visualization (8x8px color chips with hover effect)
- Brand color display with hex value
- Delete logo button
Algorithm specs:
- Skip whites (RGB > 235), blacks (< 20), grays (sat < 0.2)
- 3-6 clusters based on image complexity
- 10 iterations with early convergence
- Lightness filter (0.25-0.80 range)
- Sort by saturation (most vibrant first)
Both modes now have identical logo/branding features!
- Add shop-mode.html and project-mode.html for separate calculation
modes - Refactor index.html as a landing page for mode selection - Add
Dockerfile with optimized nginx config and healthcheck - Add
.dockerignore for cleaner Docker builds - Add deploy.sh for
Helm/Kubernetes deployment automation - Add helm-chart/ with
values.yaml, Chart.yaml, templates, and documentation - Update README.md
with full instructions, features, and CI/CD examples
