Note

Low Risk
Documentation-only translation updates adding new pages and expanding examples; no runtime code or behavior changes.

Overview
Adds new create/personalization.mdx pages in Spanish and French documenting user-specific personalization (MDX user data, page visibility via groups, and OpenAPI filtering via x-mint/x-mint-enum).

Updates Spanish/French deploy/authentication-setup.mdx to reference the new personalization docs and expand the User data format/examples to include content and apiPlaygroundInputs (plus minor wording/formatting tweaks in auth sections).
