   COMPONENTS.CSS — Reusable UI Components
   KD Excavating v2 | Noir Studio

   Every class here is self-contained. Components know nothing
   about where they live on the page — layout files handle
   positioning. A .btn works the same in the nav, hero, or
   footer without any overrides.

   Sections:
     1. Buttons
     2. Typography Components
     3. Nav
     4. Ticker
     5. Service Row
     6. Why / Review Items
     7. Metric Cells
     8. Contact Info Items
     9. Contact Form
    10. Footer
    11. Chat Widget
