Mouse wheel up/down smoothly zooms the camera in and out. Zoom range: close-in overview (5 high, 4 back) to wide survey (16 high, 12 back). Default sits at midpoint (10 high, 8 back) matching the previous fixed offset. Configurable via min_zoom_offset, max_zoom_offset, and zoom_step exports. Zoom interpolates with the same follow_speed as position tracking for consistent feel.
