/**
 * /index4.php: "The Hinge", a homepage candidate built to
 * .scratch/index1-homepage/copy-spec.md and .scratch/homepage-layouts/index4/vibe-spec.md.
 *
 * One hinge runs down the page. Left of it the workshop as it lives now: thin,
 * grey, overlapping fragments with their own small chrome. Right of it the same
 * moment in Workshopr: one solid warm card. In the hero the hinge is a range
 * input that moves the split. index-new.css loads first for the account dialogs
 * and the .tue-page ground (paper grid, type reset).
