Thirteen methods on Photo, make() through gpsAltitude(), each named after its PhotoExif field and typed by it. Each calls exif() with the same opts and returns that one field, or undefined when the file lacks it. A test checks, on the JPEG fixture and on test/exif.heic, that every field exif() returns has a method giving the same value. README and TODO.md list them. Model: opus-5-5
