/* Exhibit RSGDX — custom-banner.css — v10 (v10: slide transition switched
   from a left/right translating track to a plain crossfade — the snappy
   left/right motion read as less premium, and a fade felt calmer/more
   in line with the rest of the site. Slides are now stacked absolutely
   inside the track and toggle visibility via opacity + the is-active
   class, controlled by custom-banner.js.)
   (prior: v9 — desktop height trimmed slightly so the next section peeks
   at the bottom of the viewport instead of the slider owning the entire
   screen; added a dedicated tablet band (768–1199px) between the desktop
   and mobile breakpoints — tablets previously fell through to the desktop
   "100vh minus header" height, which reads as far too tall for a
   portrait/landscape tablet viewport and made the banner image look
   stretched/oddly cropped.)
   (prior: title font-size settings/responsiveness, buttons, arrows, dark overlay, lights toggle — all working)

   Buttons use the shared .exhibitrsgdx-btn classes from custom-style.css.
