/*
 * DATAWISE Application Layout System
 * Version: 1.0.0-dev3
 *
 * Purpose:
 * - constrain small/medium ERP screens on ultra-wide monitors
 * - keep DWGrid fluid inside its parent
 * - support 1/2, 1/3 + 2/3, 1/4 + 3/4 page layouts
 * - remain independent from DWGrid core CSS
 * - avoid Bootstrap .container/.row/.col naming collisions
 *
 * Usage:
 *   <div class="dw-app-layout dw-app-layout--normal">
 *       ...
 *   </div>
 *
 * Width presets:
 *   --compact : 1180px
 *   --normal  : 1480px
 *   --wide    : 1760px
 *   --xwide   : 2080px
 *   --fluid   : no max-width
