feat: define cross-platform posting and linking policy for the two-door model

[ibloud]

Problem or opportunity

The project needs a written rule for how Patreon and Urban Alien Adventures reference each other so the two-door model stays coherent without becoming fragmented or repetitive.

Proposed solution

Define a cross-platform posting and linking policy. The default should be light acknowledgment between doors, with core content remaining native to its platform unless later reused in milestone recaps or summary posts. Include guidance for footer language, cross-links, and avoiding duplication.

Acceptance criteria

• Cross-platform linking policy is defined
• Default repost/reuse rule is defined
• Footer or CTA language guidance is defined for both platforms
• Duplication avoidance rule is defined

This policy should support 'two doors, one project' without letting one lane cannibalize the other.
