📖 LiveScreen Client-Side Apple Live Photo Dual-File UUID & QuickTime Muxing Architecture

LiveScreen is a 100% client-side Video-to-iOS-Live-Photo and Dynamic Lock Screen Wallpaper workbench powered by WebCodecs hardware H.264 encoding, Canvas 2D, and a zero-dependency binary muxer that uploads 0 bytes to any server.

LiveScreen implements Apple ImageIO and AVFoundation binary pairing rules by writing Big-Endian TIFF and Apple iOS MakerNote 0x0011 (ContentIdentifier) into the cover .JPG while muxing com.apple.quicktime.content.identifier and a 9-byte mebx still-image-time timed metadata track into the companion .MOV across 4 languages.
