 * Laptop-height fix: the hero was tuned against wide desktop monitors
 * (~1080px+ tall), but common laptop viewports (1366x768, 1280x800,
 * 1440x900) are wide enough to hit the title's max font-size yet far
 * shorter — the vw-driven spacing above doesn't know about that, so the
 * content stack ends up taller than the viewport and the stats row
 * collides with the scroll indicator. Compact the vertical rhythm (using
 * svh, which *does* track viewport height) and drop the purely decorative
 * scroll indicator whenever height is tight. min-width guards this so
 * phones in portrait (short but narrow) are unaffected.
