// macOS gets NSColorSampler (see macos/Runner/ScreenColorSampler.swift) and
// Chromium browsers get the EyeDropper web api. Both of those draw their own
// magnifier loupe over the whole desktop and hand back a single colour when
// the user clicks, so theres no live preview to stream on the way - the
// preview IS the loupe.
//
// Everywhere else [nativeEyedropperAvailable] just answers false and callers
// fall back to sampling the apps own frame (see widgets/app_frame_capture.dart),
// which is window-only but works on every platform.
