BroadcastChannel, storage fallback messaging, or cross-tab sync.SerialTypedEventBus when ordering and sequential side effects matter.ParallelTypedEventBus when handlers are independent and latency matters.BroadcastTypedEventBus or a cross-tab messenger for browser-tab synchronization.references/api.md for interface details, messenger fallback behavior, and examples.destroy() for long-lived UI and test code.references/api.md: Detailed package API, examples, and edge-case guidance. Load it only when the task needs TypedEventBus contracts, event handler fields, serial/parallel/broadcast examples, messenger APIs, and fallback chains.Use when implementing CoSec authentication with Fetcher, including CoSecConfigurer, JWT token lifecycle, token storage, refresh handling, device ID storage, multi-tenant space resolution, resource attribution, authorization headers, and 401 or 403 error handling.

Use when calling OpenAI Chat Completions through Fetcher, configuring OpenAI or ChatClient, sending streaming or non-streaming chat completion requests, adding interceptors, using completion result extractors, or handling OpenAI client errors.
Use when generating type-safe Fetcher API clients from OpenAPI 3.x specs, including fetcher-generator CLI usage, CodeGenerator API, GeneratorConfiguration, parse and generation pipeline, model generation, client generation, barrel exports, and Wow CQRS generation support.
