/* The brand CTA uses a 6-stop gradient that traces the logo tooth icon
   left-to-right (coral -> yellow -> sage -> teal -> navy -> purple). The
   yellow stop is intentionally narrow so the white text never sits on a
   low-contrast band. Hover slides the gradient position for a subtle
   "alive" feel. Exact colours sampled from Assets/simbolo@4x-8.png.

   90deg keeps the gradient bands perfectly vertical — a diagonal angle
   on a wide pill button creates a visible coral wedge on the bottom-left.
   background-clip: padding-box stops the gradient from leaking into the
   transparent border the base .btn rule paints. */
