  *   - Adds HttpsProxyAgent import to http-helpers/index.js
- *   - Injects proxy agent into every axios request to polymarket.com
+ *   - Registers an axios interceptor that injects the proxy agent
+ *     into every request to polymarket.com
  *   - Reads PROXY_URL from process.env at runtime
- *
- * Uses regex matching so it works regardless of code formatting
