/* rPBX admin interface
 *
 * Design rules:
 * - full-viewport application shell, never a centred marketing page;
 * - compact vertical rhythm so a 1080p screen shows a working set of rows;
 * - one accent colour, restrained status colours, mono for numbers/IDs;
 * - master-detail and data grids instead of nested panels;
 * - one primary action per page, secondary actions in an overflow menu.
