Detailed Description

Declarative UI widget for visualizing a single stream with overlays.

This header declares stream_cell, a Qt widget that:

• displays video frames (from a media player or camera),
• supports interactive drawing of "draft" lines in percentage coordinates,
• renders persistent (saved) lines on top of the video,
• shows transient event markers (e.g. motion/tripwire hits),
• emits signals for user actions (close/focus) and frame availability.

The implementation lives in stream_cell.cpp.
