Company registration

Create the account, choose seats, then continue to checkout.

Registration creates the owner identity through Supabase, creates an Arkitech organization through the API, then sends billing to Polar.

Checkout handoff previewAccount setup, organization details, plan selection, and Polar checkout in one guided flow.

Your sign-in identity uses Supabase Auth and can later access the organization dashboard and desktop bootstrap.

The owner account creates the workspace, default billing role, and initial seat capacity.

Polar handles checkout and customer portal access. Arkitech remains the seat and entitlement authority.
