/* Home board (HER-10): Gridstack tile layout, widget panels, info tiles, quick actions.
   Minimalist refresh: the board chrome (panels, headers, quick-action cells, config) is intentionally
   MONOCHROME and derived from currentColor — color-mix(... currentColor ...) yields borders/tints that
   flip automatically with the active theme's text colour, so the board reads correctly in light AND dark
   WITHOUT depending on --dxbl-* tokens (the DevExpress Fluent theme does not expose --dxbl-primary /
   -border-color / -panel-bg, so the old fallbacks were in fact the only values ever applied). Colour is
   reserved for DATA: the info-tile status fills and the embedded dashboard's chart.
   Info-tile fills are the user-picked DefaultColor / threshold-rule colours applied inline by KpiWidget,
   with a per-tile contrast foreground (ColorCss.ForegroundFor) — deliberately NOT theme-derived so a
   chosen colour reads identically across themes; do not convert them to theme variables. */
