Changed #

• Updated Node.contains to accept EventTarget? instead of Node?. This fixes issues where event.target could not be passed directly to contains.

Initial release of the server-safe Web API abstraction.

Global singletons

• window — Pre-initialized Window instance

Factory functions

Server implementations

• All types are no-ops or provide Dart-native fallbacks
• Storage backed by Map
• Crypto.randomUUID() via dart:math
• btoa/atob via dart:convert
• Performance.now() via Stopwatch
• Clipboard stores text in memory

Browser implementations

• All types wrap package:web DOM objects
• .raw property exposes the native JS object
