ZoomIndicator class

Two-line zoom HUD: numeric zoom factor on top, human-readable lens label below (e.g. Wide camera, Ultra wide camera). Sits above the lens picker in YOLOShowcase.

Styling pulled from yolo-ios-app/Sources/UltralyticsYOLO/YOLOView.swift#setupUI:

  • labelZoom.font = UIFont.systemFont(ofSize: 12, weight: .semibold) — numeric reading.
  • lensCaptionLabel.font = UIFont.systemFont(ofSize: 11, weight: .medium) — caption.
  • lensCaptionLabel.textColor = UIColor.white.withAlphaComponent(0.78).
