[anton5267]

Goal

Move the current source repository from Timurc390/Boardly into the boardly1 organization.

Current blocker

The authenticated account has write access to Timurc390/Boardly, but not admin access. GitHub requires repository admin/owner permission to transfer ownership.

Checklist

• Ask the current owner to transfer Timurc390/Boardly to boardly1.
• Accept the transfer as an organization owner if GitHub asks for confirmation.
• Verify the default branch and repository settings after transfer.
• Apply team permissions from docs/ACCESS_MODEL.md.
