/* ==========================================================================
   COMPONENTS
   Reusable UI patterns repeated across pages: buttons/CTAs, cards,
   pull-quotes, and form controls (Contact + Booking Form pages).

   v2 (visual redesign pass): pill-shaped buttons with a hover lift + press
   state, a new .card component for paired content blocks, a pull-quote
   treated as a quiet callout with a decorative quote mark, and form
   controls with a custom select arrow and a proper focus glow.
   ========================================================================== */

/* ==========================================================================
   BUTTON / CTA
   One base class + three color variants. Used for every button-styled
   link on the site (hero CTAs, "Learn more", "Arrange Meetings", etc).
   Text-transform: uppercase is applied here in CSS so every button reads
   consistently regardless of how the source copy was capitalized — the
   underlying HTML text is untouched.
