summary
Demos show concrete wins: direct edits to disk with the File System Access API (no upload/download and explicit edit permissions), native file sharing via Web Share API Level 2 (shares actual blobs to Teams/Airdrop), contact selection with the Contact Picker (mobile-only, user chooses fields), resilient uploads/downloads via Background Fetch in service workers, and GPU-accelerated browser inference with WebGPU (claimed jump from ~500 to ~8,000 FPS for a 3D render). Browser support and mobile limits are spelled out.
