 ### Core Components
 
-- **`FetchClient`** - Main HTTP client class with typed JSON methods (`getJSON`, `postJSON`, etc.)
-- **`FetchClientProvider`** - Singleton pattern for shared configuration, caching, and rate limiting across multiple client instances
-- **Middleware System** - Pipeline architecture using `FetchClientContext` and `next()` functions
-- **Rate Limiting** - Built-in middleware for HTTP 429 responses with `Retry-After` headers

 - **Caching** - Key-based response caching with TTL support

 ### Key Patterns
 
 **Provider Pattern**: Use `FetchClientProvider` for shared state:
+
 ```typescript
 const provider = new FetchClientProvider();
 provider.enableRateLimit({ maxRequests: 100, windowMs: 60000 });
 const client = provider.getFetchClient();
 ```
 
 **Middleware Chain**: Always call `next()`, modify `context.response` after:
+
 ```typescript
 provider.useMiddleware(async (ctx, next) => {
   // pre-processing

 ## Development Workflow
 
 ### Essential Commands
+
 - `deno task test` - Run tests with network access
 - `deno task build` - Generate NPM package in `./npm/`
 - `deno task check` - Type check all TypeScript files
 - `deno lint` and `deno fmt` - Linting and formatting
 
 ### Testing Patterns
+
 - Use `FetchClientProvider` with `fakeFetch` for mocking
 - Rate limiting tests require `await delay()` for time windows
-- Cache tests use `provider.cache.has()` and `provider.cache.delete()` for assertions
+- Cache tests use `provider.cache.has()` and `provider.cache.delete()` for
+  assertions
 - Middleware tests check `ctx.response` before/after `next()`
 
 ### File Organization
+
 - `src/` - Core TypeScript source
 - `mod.ts` - Main export file
 - `scripts/build.ts` - Deno-to-NPM build configuration
 - Tests are co-located (`.test.ts` suffix)
 
 ## Critical Implementation Details
 
-**Context Mutation**: Middleware modifies `FetchClientContext` in-place. The `response` property is null before `next()` and populated after.

-**Error Handling**: Uses `expectedStatusCodes` array instead of try/catch for HTTP errors. `errorCallback` can suppress throwing.
