Ticket: TINYDOC-3671

Site: Staging branch

Changes:

• tinymceai-on-premises-early-access-note.adoc: deleted the stale early access note and removed its three includes.
• tinymceai-introduction.adoc: noted that the API is also available from the on-premises service, and linked the On-Premises Deployment section to the on-premises overview.
• tinymceai-integration-options.adoc: replaced the note in the On-Premises Deployment cell with a short description and links to the on-premises overview and Getting started guide.

Pre-checks:

• Branch is correctly prefixed:
• Files removed have been deleted, not just excluded from the build (if applicable).
• Build passes without console errors, warnings, or issues.

Review:

• Documentation Team Lead has reviewed.
