Project Charter - Customer Portal Revamp

Goal: Give customers self-serve access to their invoices and support tickets
without emailing support.

In-scope deliverables (4):
1. Self-serve invoice + ticket view
2. SSO login
3. PDF invoice download
4. Admin mirror view for support

Explicitly out of scope: chat widget (deferred to phase 2).

Stakeholders: Sarah (sponsor), Marcus (dev team lead), Noor (support lead).
Timeline: ~10 weeks. Budget: not yet finalized.
Risk: SSO integration with the old identity provider may take longer than expected.
