 * Roofing landing page.
 *
 * Committed to a single light treatment rather than following the system theme.
 * A landing page is a brand surface that gets screenshotted into ad reviews and
 * compliance files, and a consent disclosure that renders differently for
 * different consumers is a worse problem than a dark mode nobody asked for.
 *
 * Mobile first throughout: the traffic is a homeowner standing in a driveway
 * looking at their roof, not somebody at a desk.
