 * 375px viewport the document measured 397px wide (2026-09-16). Several pieces
 * are meant to sit outside the layout (the hero glows, the fanned mockup cards,
 * the testimonial marquee), so the page is clipped here instead of changing the
 * design. `clip` does not create a scroll container, so the sticky header keeps
 * working; `hidden` is the fallback where `clip` is unsupported.
