How do I install DEV3 Mailtide step by step?

Install

1. Upload the mailtide folder and point your domain at mailtide/public.
2. Open the site. The wizard at /install checks requirements, writes .env, migrates, loads demo data or an empty install and creates the operator account.
3. Add the cron entry. The scheduler sends campaigns, advances automations and re-checks domains.
4. Sign in at /admin (operator) or /app (workspaces).

Node.js is not needed: compiled assets ship in public/build.
