 * Shared manual left/right arrow scroll controls (added 2026-08-12).
 * Currently used by Flash News and Happenings in PU. See
 * wp-content/PATCHES/2026-08-12-scroll-arrows.md
 *
 * Buttons refined 2026-08-13 (see
 * wp-content/PATCHES/2026-08-13-mega-menu-columns-and-more.md) — the
 * original text-glyph arrows (‹ ›) read as thin/unpolished; swapped for
 * inline SVG chevrons (in pu-scroll-nav.php) with a slightly more
 * deliberate button treatment (soft shadow, subtle press/hover motion)
 * so they read as an intentional control, not an afterthought.
