# Baby in Brazil CTA product documentation seed

This patch adds a product-specific documentation guide for `mod-bib-cta` on the public extension documentation page.

The documentation is rendered through `DocsController::extensionDocumentation()` because the current public documentation model is template-driven rather than stored as editable CMS records. The migration updates the CTA extension summary and seeds platform changelog entries so the change is visible in the system changelog.

The guide covers:

- what the CTA module is for;
- the structured content model;
- actions and button guidance;
- presets and adaptive CSS Grid behavior;
- styling and template integration;
- recommended setup workflow;
- troubleshooting;
- FAQ;
- related ExtensionFlow documentation links.

Platform version is bumped to `0.9.3-dev` because this is a public documentation feature, not only a text edit.
