/* =========================================================================
   buttons.css — Sistema canônico de botões
   =========================================================================
   v1 (pai-review-full-v1 §5.5) — classes semânticas simples
   v2 (dashboard-phi-foundation) — 4 tamanhos + 4 variantes BEM, estados
     físicos com spring, focus-visible, glow accent.

   HIERARQUIA v2 (BEM):
     .pai-btn          — base (shape, padding, transição, touch target 44px)
     Tamanhos: .pai-btn-xs | .pai-btn-sm | .pai-btn-md | .pai-btn-lg
     Variantes v2: .pai-btn--primary | --secondary | --ghost | --icon | --danger

   LEGADO (v1, preservado 100%):
     .pai-btn-primary / .pai-btn-secondary / .pai-btn-danger / .pai-btn-ghost
     .pai-btn-sm (modificador tamanho)
     .pai-btn-icon (modificador forma)
     Classes .btn/.btn-primary/etc — aliasadas.

   Regra: usar v2 em código novo. Manter v1 em telas existentes até serem
   refatoradas pelo Change E.
