/* vx-datamap.css — the handful of classes the Data Map markup uses that Bootstrap 5 does not
   define. Everything else in the markup is plain Bootstrap 5 utility/component classes.
   Ported from VXconnect.Admin.UI/wwwroot/css/common.css's "Data Map Editor" and "Expression
   Builder Modal" sections, trimmed to the classes actually referenced by the moving markup and
   using only standard Bootstrap 5 CSS custom properties (--bs-*) so it is host-neutral. Host
   chrome — icon sprites (v1-icon), themed icon buttons (btn-icon), page-header layout
   (content-header) — stays in the host per the design's "host chrome stays in host" rule and is
   deliberately not reproduced here. */

/* ── Modal stacking ───────────────────────────────────────────────────────────
   These modals render inline, inside the host's page content, so they compete
   with the host's own header for paint order. The VXconnect Utility Portal's
   header is `position: sticky; z-index: 1030`, which sits above Bootstrap's
   default modal z-index of 1055 in practice, clipping the dialog title.

   Bootstrap already exposes the value as a custom property, so raise it rather
   than hard-coding a z-index and fighting the framework. 1080 clears both the
   1030 header and Bootstrap's own 1070 tooltip layer, while staying below the
   toast layer at 1090. */
