mail_layout_preview

Purpose

Allow developers to see full-layout browser previews of email templates instead of the backend-wrapped version.

Features

mail.template.preview: Adds a full layout preview URL on the template preview wizard pointing to the rendered output for the selected record.
mail.template: Exposes an HTTP endpoint that renders a template’s HTML body for a chosen record so the actual email layout can be inspected in the browser.
mail: Provides a browser page listing all email templates for a given model with instructions and preview links.
