Reveal

import Reveal from "@dertour/ui/components/common/Reveal/Reveal"

Scroll-reveal wrapper: fades + rises its children into view the first time they enter the viewport, once. Must sit under a `MotionProvider` (`LazyMotion` + `MotionConfig`), which also makes it honour prefers-reduced-motion (Motion then skips the transform and just shows the content). A full-width block so it never disturbs a section's own layout.
