renderer-simple
Default renderer plugin for kind="notification": takes a structured EmailTemplateData variable map (with header, sections[] of text/button objects, and optional footer; falls back to title/body if no structured fields are present) and returns rendered HTML with inline CSS. Requires renderer-foundation; sufficient for plain notification emails — swap it for renderer-mail-html if you need MJML/Markdown layouts.
