 ## Gotchas
 
 - **`.js` extensions in imports**: All worker imports use `.js` extensions (`import { foo } from './bar.js'`). Required for ESM resolution with `moduleResolution: "bundler"`.

-## Banner Configuration
-
-Set environment variables in `wrangler.toml` or Cloudflare dashboard:
-
-```toml
-[vars]
-STATUS_BANNER_URL = "https://example.com/banner.png"
-STATUS_BANNER_LINK = "https://example.com"  # optional
-```
-
-- Banner replaces title text when `STATUS_BANNER_URL` is set
-- Title is used as `alt` text for accessibility
-- Link opens in same tab when `STATUS_BANNER_LINK` is set
-- Empty or unset URL falls back to title display
