   viewport, which inflates the page's horizontal scrollable width and breaks

/* Responsive Guardrails & Multi-Line Text Wrapping Prevention
   Forcing `white-space: nowrap` on long button/badge labels (e.g. "Explore

   real horizontal overflow on narrow phones — the label refuses to wrap, so
   its flex/inline-flex container is forced wider than the viewport. Only
   force the single-line look at sm+ (640px), where there's room for it;
   below that, let text wrap normally. */
