Added tests/Unit/PersonaPagesTest.php and the folder resources/marketing/personas/. The test reads each persona page file alone: its keys, its sections, the areas, capability pages and screens it names, its Help articles and fact tokens, balanced app marks, no dash characters, no mention of the app outside its marks, no area that is not open, and a row in the checklist in PERSONA_PAGES.md. The plan now says how a content session writes a page before the renderer exists. Nothing on the website changes with this entry.
A check for persona page content files
Added the test that checks each persona page content file on its own, so the pages can be written before their renderer is built.
