/**
 * Progress bar concern — slider-bar DOM construction, chapter-marker rendering,
 * scrub helper types, and the time-formatting utility.
 *
 * Integration: `buildSliderBar()` returns `SliderBarRefs`. The plugin class
 * keeps the refs as instance fields and passes them into the chapter-marker
 * renderer and update helpers below. Event wiring (`wireSliderBar`) stays on
 * the class because it closes over both `this` state (isMouseDown, isScrubbing)
 * and the plugin lifecycle (`this.listen`, `this.timeout`).
