Chapter Features

Each feature is a chapter. The active one opens to its full description while a thin rail fills in time with the autoplay clock; when the rail is full the next chapter begins. Hover, keyboard focus or scrolling the section out of view pauses it, and any chapter can be opened directly.

Beside the list, a stage wipes upward to that chapter’s scene. The built-in scenes are small product moments rather than icons: a search that types itself and returns results, permissions switching on one by one, a chart whose bars grow into place, and a deploy log that ticks through its steps to Ready.

Pass a visual per chapter to show your own screenshots or UI. Light and dark (.dark), one CSS file, no animation library; under prefers-reduced-motion it stops autoplaying and shows each scene in its finished state.
