- ClientCard.tsx: server component with name, email, doc count, last activity; wrapped in Link to /portal/clients/[id]
- ClientModal.tsx: use client component with useActionState from react; supports create/edit modes via bind pattern; closes on success
- ClientsPageClient.tsx: use client wrapper holding isOpen modal state, renders card grid or empty state CTA
- clients/page.tsx: async server component fetching clients with docCount + lastActivity via Drizzle LEFT JOIN + GROUP BY
