This is the whiteboard. Ink lands here, decoupled from the camera view.
Point with your index finger (other fingers relaxed/curled)
to draw. Open your palm (all fingers extended) to erase
around your hand. Pick tool/size from the toolbar in the panel — that's
the only way to change them now.

Board calibration
Maps your pointer onto the whiteboard plane so drawing stays accurate off-center or at an angle. Optional — works uncalibrated too.

Physical Pen Mode
Automatic (v4.4): tracking switches to a detected pencil/pen tip on its own when one is held in frame, and falls back to your fingertip when it isn't — no toggle needed. Experimental (may misfire in cluttered/low-contrast scenes, see README); the checkbox below is an optional manual override plus the HSV color-calibration accuracy boost.
