Goal
Support a focused template-inheritance mechanism for a child template to select a parent layout and provide content for one or more named slots.
Example direction:
{% layout "parent.tpl" %}
{% block content %}<h1>Hello</h1>{% endblock %}<html>
<body>{% slot content %}Default content{% endslot %}</body>
</html>The final syntax should be chosen against an established implementation such as LiquidJS or Jekyll and documented as an extension when it is not part of Shopify Liquid.
Acceptance criteria
- Define the compatibility target and exact syntax before implementation.
- Support a default body and at least one named block/slot.
- Resolve layouts through
TemplateStore and the same path rules as other template-loading tags.
- Define variable scope between child and parent templates.
- Detect missing layouts, duplicate blocks, and inheritance cycles with source-located errors.
- Include focused tests and user-facing documentation.
Pull request guidance
Implement this as a focused change. PR #145 combines layout support with many unrelated compatibility, audit, sandboxing, and API changes and is not a mergeable implementation path for this issue in its current form.
