/*
 * Category showcase -- "What are you researching?"
 *
 * A horizontally scrolled row of category cards, each previewing four products.
 * The track is a real scroll container: swipe, trackpad, keyboard and the arrow
 * buttons all drive the same scrollLeft, and the bar underneath is a custom
 * scrollbar drawn over it rather than a separate pagination control.
 *
 * Two presentations, set by a modifier on the section:
 *   .ken-showcase--peek   next card partly visible, so the row reads as scrollable
 *   .ken-showcase--center one whole card centred, nothing beside it
 * Everything except the item width and the snap alignment is shared.
 *
 * Colours are the theme's own tokens; this file introduces no new palette.
