/* Catalog style "demo48" — the album as one rail: dark DEPO product UI, Poppins + Lato, demos in a horizontal snap row with a thin progress line. Mirrors /demo48/ (Connect · Spotlight: the card under the pointer lifts, the rest of the row steps back); based on the demo41 style. */
/*
 * Layout: a rounded glass banner card (brand, tagline, count) like the banner of /demo48/; the
 * style bar is a second, quieter card with the URL in a field and a green Copy pill; categories
 * are pills with count chips. The list is the demo's rail: a section head (title + count chip +
 * range) and one horizontal row of cards that bleeds to the window edge, snap-scrolling, with a
 * thin scrollbar styled as the rail's progress line. On a post the page is a single column of
 * cards. No JS: the rail is plain CSS overflow + scroll-snap.
