    list_categoriesList all rule categories in the Email Playbook with a one-line description and page count. Categories are: structure (head/body container/header/body/footer), compatibility (Outlook MSO, RTL, responsive), production (Gmail clipping, dark mode, preheader, bulletproof buttons), ai-generation (constraints for AI emitters). For reusable components, use list_components instead — they live in a separate dimension and are not returned by get_playbook_rules.
    get_playbook_rulesReturn the full rule pages for a given category. Each rule includes the title, description, markdown body explaining the rule, and any HTML/CSS code examples from the playbook. Use this to teach a model the exact patterns for a specific concern (e.g., responsive layout).
    list_componentsList all reusable email components in the playbook with their metadata: name, subcategory (layout/media/interactive/text), description, whether they require Outlook VML, and whether they are responsive. Use this first to discover what components exist before calling get_component.
    get_componentReturn the full record for a single component: title, description, narrative body, the primary HTML pattern, list of slots (placeholders the model should fill), VML/responsive flags, and all code examples. Use after list_components to fetch the actual HTML pattern to paste into an email.
