/* --- P0.1  Tap-swallow fix (data-mandated) --------------------------------
   iOS Safari gives inline SVG a default pointer-events of visiblePainted,
   so a tap that lands on the transparent interior of the chevron/close glyph
   was ambiguous and the "next/prev/close" button did not always fire, which
   is what drove the rage-clicks in the session recordings. Making every inner
   glyph transparent to pointer events guarantees the <button> is the only hit
   target. ------------------------------------------------------------------- */
