/* ============================================================================
   touch.css — Patrones táctiles compartidos de FESv (prefijo .fx-)
   ----------------------------------------------------------------------------
   Extraídos de Shared/AppMotoristaLayout.razor (benchmark mobile-first interno).
   AppMotorista sigue usando sus clases .mot-* inline; este archivo es la versión
   genérica y theme-aware para el resto de los layouts táctiles
   (PosLayout, PosRetailLayout, PosCombustibleLayout, BlankLayout).

   Tabla de equivalencias .mot-*  →  .fx-*
   ---------------------------------------------------------------
   .mot-btn            →  .fx-btn            (+ .fx-btn-primary / -success / -danger / -outline)
   .mot-input          →  .fx-input
   .mot-select         →  .fx-select
   .mot-container      →  .fx-container      (padding-bottom:96px para barra fija)
   .mot-header         →  .fx-header         (sticky top)
   .mot-card           →  .fx-card
   .mot-app            →  .fx-app            (tap-highlight transparente, min-height 100dvh)
   (sin equivalente)   →  .fx-action-bar     (barra de acción fija inferior)
   (sin equivalente)   →  .fx-tap            (target táctil mínimo 44x44)

   Colores: se usan variables de Bootstrap 5.3 (var(--bs-*)), que fesv-theme.css
   redefine por tema, de modo que todo funciona en claro y oscuro sin overrides.
