The editor should preserve semantic structure while limiting markup that creates accessibility, design, or search problems.

1. Reserve the page H1 for the template when possible and let the editor use H2/H3 levels in a logical hierarchy.

2. Sanitize pasted HTML and remove unsupported scripts, event handlers, and excessive inline styling.

3. Require valid href values for links and offer rel options only when needed.

4. Handle images with alt text, dimensions, captions, and upload optimization fields.

5. Prevent empty headings, nested anchors, duplicate IDs, and malformed list/table structures.

6. Provide an HTML/source view or validation layer for advanced users without allowing unsafe markup.

A good editor makes the correct semantic output the easiest path. Guardrails reduce the amount of technical cleanup needed after publishing.
