/* Back-to-top button — end of publication pages (client request 2026-09-01).
 *
 * A static end-of-content button rather than a floating overlay: the pages
 * already carry a sticky section nav at the top, and a second persistent
 * floating control would compete with it on mobile.
 *
 * Accent matches the publication nav's active pill (#006FE6). White on that
 * blue is ~4.76:1, clearing WCAG AA for this 0.95rem bold label.
