   Buttons — Edge Pharma
   Base button shell + modifiers. The primary CTA (used by the nav's
   "Contact Us" button) is fully styled here per spec: 48px height, 24px
   horizontal padding, 999px radius, primary color, lift + shadow on
   hover. Every other modifier, plus Pagination and Tabs, remains a
   structural shell to be finished in a later step.
