 ## Security & Configuration Tips
 - Keep secrets in `.env.local`.
-- UploadThing: `UPLOADTHING_SECRET` (required), optional `UPLOADTHING_APP_ID`; TTLs `FAVICON_TTL_SECONDS`, `SCREENSHOT_TTL_SECONDS`.
-- Screenshots (Puppeteer): prefer `puppeteer-core` + `@sparticuz/chromium` on Vercel; optional `PUPPETEER_SKIP_DOWNLOAD=1` to avoid full download; `HOOT_USER_AGENT` to override UA; optional `PUPPETEER_EXECUTABLE_PATH` locally.
+- Screenshots (Puppeteer): prefer `puppeteer-core` + `@sparticuz/chromium` on Vercel.
 - Cache Cloudflare DoH, RDAP, TLS, and header probes via `lib/cache`; apply retry backoff to respect provider limits.
 - Review `server/trpc.ts` when extending procedures to ensure auth/context remain intact.

 3. **(Optional) Configure `.env.local`:**  
    See `.env.example` for Redis and UploadThing credentials (needed for caching and favicon/screenshot features).
 
-   Useful keys:
-   - `UPLOADTHING_SECRET` (required)
-   - `UPLOADTHING_APP_ID` (recommended)
-   - `FAVICON_TTL_SECONDS`, `SCREENSHOT_TTL_SECONDS` (optional TTLs)
-   - `HOOT_USER_AGENT` (optional UA override)
-   - `PUPPETEER_SKIP_DOWNLOAD=1` on Vercel to skip full `puppeteer` download
