   3D PRINT & ENGRAVE PRO - MAIN STYLESHEET
   Color Scheme: Dark Blue (#1a2a4a), Silver (#c0c0c0), Red (#dc3545)

   IMAGE OPTIMIZATION TIPS:
   - Use WebP format for best compression (fallback to JPG/PNG)
   - Gallery images: 800x600px for thumbnails, 1920x1080px for full size
   - Hero images: 1920x1080px minimum
   - Use srcset for responsive images
   - Compress images with tools like TinyPNG or Squoosh
   - Consider lazy loading for gallery images (loading="lazy")
