CommanderCam — the commander's view of the Kessrel Line. A camera behaviour for the PlayerPrototype's CameraRig: an elevated station behind the human line, pitched down, looking north along +Z up the canyon, so the Gate sits at the bottom of the frame and the tide pours down from the top. The composition is key-art.png — the line low, the tide filling the middle, the Maw and the low sun near the top with a band of sky over them — and the fields below are that composition written down. Panning moves the anchor; zooming walks the station along the sight line. Neither turns the camera: the heading is fixed north, so the canyon never rolls under a player who is reading a battle. The Command component writes `anchorX` / `anchorZ` / `zoom`; everything else is the composition. The lens answers to the SHAPE of the screen. Vertical field of view is held so the vertical composition is the same on every device, and a screen too narrow to show a useful width of the line widens the lens rather than cropping the line — so a phone held upright still sees regiments either side of the one it is centred on, and a television simply sees more canyon.
