/* Soundgun web — the landing page itself.
 *
 * The design is a scroll film: three sections are taller than the viewport and pin a
 * 100vh stage while the page scrolls past them, and app.js drives the stage from the
 * section's own scroll progress. That only works when there is room to pin into, so
 * every pinned scene has a flow-layout twin below the --unpin breakpoint: same markup,
 * same copy, laid out as ordinary stacked blocks. Nothing is hidden on small screens.
