TermosFloatingSlider class

Tick-strip slider that looks identical to TermosSlider at rest but supports continuous horizontal dragging. While dragging, the selected notch detaches and morphs into a circle; as it approaches another notch it morphs back into a tick. On release, the indicator snaps to the nearest discrete position.

First and last notches are inset by edgePad so that labels are centred under them regardless of notch count.

Constants

edgePad → const double
Horizontal inset for the first and last notch so edge labels stay visible.
