Consolidate CSS architecture and eliminate repetition

- Add CSS custom properties for commonly used gradients
- Consolidate duplicate button variants (.btn.active and .btn-success)
- Replace inline gradient styles with semantic CSS classes
- Standardize spacing with utility classes (mr-1, mr-2, mr-4, ml-3)
- Remove unused Home.module.css file
- Replace hard-coded colors with Solarized CSS variables
- Add scene-specific button classes (btn-scene-preview, btn-scene-transition)

Reduces CSS duplication, improves maintainability, and ensures consistent
styling throughout the application with reusable utility classes.
