/* Horizontal pinned scroll — the section (title + cards) stays stuck as one
   block right under the header while vertical scroll drives the track
   sideways. The block is sized to its own content (not forced to fill the
   screen) so it never reserves blank space before or after itself — it
   simply appears the moment you scroll to it and stays put while the cards
   slide by. `.hscroll` gets its runway height set by JS (script.js); without
   JS it just falls back to a normal-height section whose card row scrolls
   horizontally on its own (touch/drag/wheel). */
