   index-extras.css — index.html-specific overrides and unique sections.

   Loaded AFTER landing.css. Contains:
     - Overrides where index.html intentionally diverges from the shared rules
       (e.g. 4-column how-steps, 3-column pricing grid)
     - Interactive demo section (.demo-*)
     - 3D preview section (.preview-3d-*)
     - Workflow section (.workflow*)
     - Pricing card variant (.pricing-card-new, .pricing-price-new, etc.)
