A production-grade upgrade of Browser API Lab: unified capability scanning, top-level browser environment snapshot, and new WebAuthn/WebGPU read-only playgrounds.
- Added a new Browser Environment Snapshot panel: user agent, platform, brand/version, viewport, DPR, secure-context status, hardware concurrency, languages, touch points.
- Implemented a fully hydration-safe detection architecture using effect-driven state transitions (no server/client mismatches).
- Expanded the capability scanner to 8 APIs: Notifications, Web Share, Clipboard, Geolocation, Service Worker, EyeDropper, WebAuthn, WebGPU.
- Introduced WebAuthn read-only playground: platform authenticator detection, conditional UI availability, minimal credential-creation example.
- Added WebGPU read-only playground: navigator.gpu detection, adapter/device example code.
- Refined two-column layout to match Birdor Tools design: left = capability scanner, right = interactive playgrounds.
- Improved stability across Chrome, Safari, Edge, and Firefox with unified capability models.
- Playgrounds now expose developer-oriented debugging info and safe example code.
