/* Bento — reference kit (Tastefolio). Modular modern: every page is a grid of rounded tiles with one shared gap;
   each tile holds exactly one idea (a stat, a feature, a form, a chart). Tiles span 1–6 columns and 1–4 rows,
   dashboards can be resized in an edit mode, even the header is three tiles. Requires tokens.css. RTL-safe. */
