   width matching the slider itself, so content never restyles or
   re-centers as the wrapper narrows, it's simply not painted past the
   wrapper's edge. This physically stops rendering outside the box rather
   than relying on a clip shape lining up with centered content, which is
   what caused the two panels' text to overlap before. */
