What it does

Writes a TEXT file to the user's hosting website (HTML/CSS/JS/JSON/SVG) — creates it or overwrites. Live immediately. No SFTP/SSH needed. IMAGES/BINARIES are not written here and base64 is not embedded in HTML. Passing image bytes through chat (as base64) burns huge amounts of tokens and can exhaust the context. site_fetch(url, 'assets/img/x.webp') downloads the file SERVER-SIDE (the bytes never enter the conversation), and HTML references it as <img src="/assets/img/x.webp">.
