   except padding tightened 6/12 -> 3/7, type 14/22 -> 13/20, radius
   10 -> 8, a tooltip-bg plate,
   one text color across both themes (the plate stays dark in light and dark
   mode). Behavior (fixed positioning off the anchor rect) is local — the
   upstream Floating stack is intentionally not vendored. */
