179- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: "/place/to/redirect" }})` instead of `Response.redirect` which is broken
180- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead
181- **AI Image:** To inline generate an AI image use: `<img src="https://maxm-imggenurl.web.val.run/the-description-of-your-image" />`
182- **Storage:** DO NOT use the Deno KV module for storage
183- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods
