   Plomberie Adel inc – Modern UI CSS

   Notes:
   - Keeps compatibility with your existing HTML classes (about, feature, service, etc.)
   - Uses Bootstrap CSS variables where available; maps to a new, brand-consistent palette.
   - Adds motion-safety, accessibility tweaks, smoother transitions, refined spacing.
   - Includes dynamic, but lightweight effects (hover, focus, reveal-ready classes).
