/* ===== Hand cursor: whole grid + horizontal scrollbar (round 5) =====
   Requirement: hovering the data table area - rows through the horizontal
   scrollbar - must show the hand cursor. Chromium always shows the arrow over
   scrollbar areas (verified on Chrome 154: even a ::-webkit-styled bar with
   cursor:pointer on the element AND on the scrollbar pseudo-elements keeps the
   arrow), so the bar is replaced with a real DOM bar rendered by
   wwwroot/js/blazor/grid-hscroll.js, whose elements do honour cursor:pointer.
   The first rule puts the hand on every grid descendant; the part rules below
   are the no-JS fallback for the native bar. */

/* DOM replacement bar (grid-hscroll.js): hide only the native horizontal bar,

   The MudBlazor theme injects `html, body * { scrollbar-color: ...;

   Chromium ignore every ::-webkit-scrollbar rule (that is why no CSS-only
