/* ---------- full-bleed invitation gates on phones ----------
   Portrait screens: the artwork covers the whole viewport instead of
   letterboxing inside a fixed-ratio frame with dark bars. The art's own
   ratio (≈0.46) matches phone viewports almost exactly, so cover crops
   nearly nothing and the % hotspots stay on their buttons. Landscape /
   desktop keeps the fitted frame so nothing important is cropped away. */
