Measured entry

ruixen-chapter-scrubber

formunclassifiedmotion on file

A client-side React chapter rail that magnifies ticks around the pointer and reveals a contextual preview card. It ships as a shadcn registry TypeScript component, uses Motion for animated values and springs, and assumes Tailwind theme tokens plus the shared cn utility.

Verdict

It builds and mounts in the prepared harness, and automated accessibility checks found no violations, but every captured viewport was blank and the narrow view overflowed. Treat the visuals as unverified. It needs a shadcn-style setup and is not ready for a bare React drop-in.

Use it if

  • You need a compact chapter or activity navigator for a long ordered sequence.
  • Your interface supports pointer and keyboard navigation and can wire selection to scrolling, replay, or routing.
  • Your project already has shadcn-style Tailwind tokens and Motion in its client bundle.

Skip it if

  • You need a component that is visibly proven by the supplied screenshots, since every captured viewport was blank.
  • Your narrow layout cannot tolerate an absolutely positioned preview card that may overflow.
  • You want a dependency-light static index without Motion or pointer-driven behavior.
  • Your app is not set up for client components or shadcn-style utility imports.

For a non-shadcn project, add Motion, clsx, and tailwind-merge; provide the aliased cn helper; configure Tailwind with the referenced semantic color and focus-ring tokens; preserve the client-component boundary; and verify the preview positioning in your layout.
