/*
 * Surf Suite — Premium Refinements
 * ===================================
 * Final operational UX & premium perception pass.
 * Load after shell-v2.css + shell-mobile.css.
 *
 * This file does NOT redesign the system.
 * It applies surgical precision improvements across:
 *
 *   1.  Scanning & operational clarity
 *   2.  Table world-class refinements
 *   3.  KPI / dashboard system
 *   4.  Forms & data entry
 *   5.  AI-native patterns
 *   6.  Surface & elevation hierarchy
 *   7.  Interaction polish & motion
 *   8.  Empty states & microcopy
 *   9.  Operational status system
 *  10.  Typography precision
