Reading Current

A long-form sentence moves from muted to active color as a focused current crosses its real word positions.

• Identity studies
• Title treatments
• Type-led campaign moments

• A local reading current sharpens one moving passage while leaving its wake visible
• Pointer scrubbing and autonomous drift share identical bounded progress semantics
• Focus span, activation line, direction, and current response tune independently
• One semantic passage backs every decorative stream and remains fully readable
• Every live control maps to the component's own motion and rendering contract
• The protected source is a complete portable React and CSS implementation

No animation package or external preview asset is required. Layout is container-scoped and decorative motion is disabled when reduced motion is requested.

Pointer, touch, horizontal trackpad and keyboard states use the same underlying component state.

Native landmarks and controls preserve reading order, visible focus and keyboard access. Motion never carries the only meaning.
