/* =================================================================
   BUTTONS — exactly 4 variants on the entire site:
     .btn-filled              regular solid
     .btn-filled.compact      small solid
     .btn-ghost               regular clear
     .btn-ghost.compact       small clear

   .btn-filled and .btn-ghost share IDENTICAL geometry; only the
   color/bg/border-color differ. .compact modifier shrinks both
   identically. Do NOT introduce a 5th variant — use chrome classes
   (e.g. .mobile-pill) on top of one of these instead.
