Detailed Description

Minimap / overview bar showing the full recording extent.

A compact horizontal widget that renders a bird's-eye view of the entire file with a viewport rectangle indicating the currently visible portion. Clicking or dragging on the bar scrolls to that position.

Features:

• Per-channel-type RMS envelope rendered as coloured waveforms
• Event / stimulus markers shown as vertical tick marks
• Annotation spans shown as translucent overlays
• Draggable viewport rectangle for quick navigation
