daiyangyang945/UyaliBeautySDK — reverse-engineered prompt

I want this turned into a polished mobile beauty SDK project with working demo apps, not just sample snippets. The main thing should be real time camera beautification and photo processing, with natural looking skin smoothing and whitening, brighter eyes and teeth, face shaping, body shaping, and makeup presets like lipstick, blush, eyebrows, eyeshadow, and contacts. It should support more than one face in the frame when possible.

Please make the demos easy to run on iPhone, Android, and HarmonyOS, and show simple controls like sliders and preset buttons so someone can actually test every effect. On iPhone, make sure camera frames and still images both work. On Android, use the texture based camera flow and keep the fallback frame path available if needed. The host app should still own the preview while the SDK only processes the frames.

Also clean up any integration issues so the package is easy to drop into another app. If anything is unclear, check the current platform docs online and make sensible choices.
