/**
 * KNOW Builder - Units Styles
 * ✨ MELHORIAS APLICADAS
 *
 * @package KNOW
 * @version 12.0 - GPU OPTIMIZED + PRESS FEEDBACK + UNIFIED EASING
 *
 * MELHORIAS vs v11:
 *   ① touch-action: manipulation + -webkit-tap-highlight: transparent
 *      eliminam 300ms phantom delay sem quebrar scroll vertical
 *   ② Press state via CSS :active — feedback imediato sem JS
 *      (JS do units-mobile.js v5.1 reforça via rAF para iOS Safari)
 *   ③ isolation: isolate nos containers — backdrop-filter não vaza
 *   ④ .unit-card__bg: easing unificado (.16,1,.3,1) em vez de .4s ease
 *   ⑤ transition específica — NÃO usar transition:all em nenhum seletor
 *   ⑥ will-change: apenas em :hover (layer GPU pronta antes do toque)
 *      Não permanente — evita desperdício de VRAM
 *   ⑦ .card-add-animated-button: transition:all → props específicas
 *   ⑧ Lista mobile: contain:layout melhora scroll em listas longas
