/* Subito Video — public landing page.
 *
 * Look #4, DD product variant (canonized in the look library under this
 * project's former name, ClassicalReels): navy ink on off-white, one
 * warm-orange accent, Lato,
 * Apple-clean with generous whitespace. Reuses the app's tokens from
 * style.css so the page and the tool cannot drift apart.
 *
 * LAYOUT: one screen on desktop, no scrolling. Two columns — the claim and
 * the crop demonstration on the left, the way in and the reasons on the
 * right — so a visitor sees what this is AND can enter their code without
 * moving. It stacks and scrolls on phones, where scrolling is expected.
 *
 * Two signatures only: spec micro-labels, and the crop demonstration.
