What Is Codex Sites?
Codex Sites is best understood as a Codex plugin and hosted workflow for creating, saving, deploying and inspecting workspace apps, not as a generic public website builder.
Define the workflow
Write the core job, page list, filters, states, sample records and review behavior before UI polish.
Define the deployment path
Save before deploy, inspect storage and move public domain work to a repo-backed host when needed.
