For testing, are there any specific components from `src/components/` that you want me to prioritize?

For CORS in `src/app/api/chat/response.ts`, is it acceptable to restrict origin to `https://amrabed.com` and `http://localhost:3000` instead of `*`? + +## Proposed Changes + +--- + +### 1. Remove Unused Imports + +I will run `npx eslint --fix` (if an unused imports rule is configured) or write a custom script using `eslint` to find and remove all unused imports and import aliases across the `src/` directory. + +#### [MODIFY] Multiple files across `src/` + +--- + +### 2.

Address Rate Limit Bypass + +The ratelimiter currently reads `x-forwarded-for` and blindly trusts the first IP (`split(",")[0]`). This is easily spoofed by clients sending a fake `x-forwarded-for` header, which proxies append to. + +#### [MODIFY] `src/app/api/chat/ratelimit.ts` + +- Change type of `req` to `NextRequest | Request`. +- Use the built-in Next.js `req.ip` which securely extracts the client IP on Vercel and similar hosting, falling back to `x-real-ip` or the _last_ appended IP in `x-forwarded-for` if `req.ip` is unavailable. + +--- + +### 6.
