Apps Script Web App Setup

A static-ish website hosted on Google Apps Script, accessible via a stable HTTPS URL under your domain.

Constraints (Broadcom / Google Workspace)

• ANYONE_ANONYMOUS / ANYONE access blocked by domain policy — use DOMAIN
• Public Drive file sharing blocked — embed images as base64 data URIs
• No Google Sites write API — Apps Script web apps are the workaround
