/* ===========================================================================
   NOTE: do not add overflow:hidden / border-radius to .table-body-wrapper.
   Any ancestor with overflow other than visible becomes a new "scroll
   container", which breaks position:sticky for descendants (the header
   then sticks relative to that ancestor instead of the page).

   Corner rounding is NOT done with border-radius, clip-path, or mask
   on the sticky <th> itself — every one of those triggers a persistent
   browser bug where the sticky compositing layer bleeds a white sliver
   at the curved edge, worst exactly when the cell reaches its stuck
   offset (Mozilla bug 1866715 / WebKit bug 128486).

   Instead, a small overlay is painted on top of each square corner.
   The overlay is filled with the color that actually sits behind the
   table (--card-bg-color, from .container2) with a transparent
   circular cutout the size of the intended radius. This "paints over"
   the square corner to fake a rounded one, using plain background
   rendering only — no clip/mask/radius anywhere near the sticky
   element, so the buggy code path is never invoked.
