# Task summary
When a signed-in user has no workspace membership, `apps/web/app/page.tsx` currently bounces them through `/sign-in?error=no_workspace`. This is a defensive fallback, not a user experience. Build a proper onboarding flow.
## Description
### Why this exists
`apps/web/lib/auth.ts`'s `ensureUserHasWorkspace` provisions a personal workspace on first sign-in, which means the zero-workspace state should be effectively unreachable for new sign-ins. However:
- Existing JWTs minted before that provisioning logic was added do not trigger `ensureUserHasWorkspace` on refresh; only on a true sign-in event.
- A user could conceivably leave or be removed from every workspace they belonged to (no UI for this yet, but the data model allows it).
- A workspace could be hard-deleted out from under a user (no UI yet, but again — data-model-allowed).
The current behavior — redirect to `/sign-in?error=no_workspace` — is acceptable as a hidden defensive branch but is jarring for any user who hits it. We want a deliberate flow.
### The flow
1. New route: `apps/web/app/(onboarding)/welcome/page.tsx`. Server Component.
2. If user is signed in AND has zero memberships, render a one-step form: "Name your workspace". Default to `${displayName}'s workspace`.
3. Form submit calls a server action that wraps `ensureUserHasWorkspace` (lift it out of `auth.ts` into `apps/web/server/lib/provision-workspace.ts` so both the JWT callback and the server action share the same code).
4. On success, redirect to `/{newSlug}`.
5. `apps/web/app/page.tsx` redirects the zero-membership case to `/welcome` instead of `/sign-in?error=no_workspace`.
### Out of scope
- Multi-workspace flow (joining an existing workspace by invite). Belongs to `Plan-multitenant-saas-hardening/Task-workspace-invites-and-roles`.
- Workspace switcher UI. Separate task; not blocking onboarding.
## Subtasks
- [ ] Extract `ensureUserHasWorkspace` and `slugifyForWorkspace` from `apps/web/lib/auth.ts` into `apps/web/server/lib/provision-workspace.ts`. Update `auth.ts` to import from there.
- [ ] Add `apps/web/app/(onboarding)/welcome/page.tsx` with the one-step form.
- [ ] Add the server action that calls the shared provisioner.
- [ ] Update `apps/web/app/page.tsx` to redirect zero-membership users to `/welcome` instead of `/sign-in`.

## Estimation

## Acceptance criteria
- [ ] Signing in with a session that has no membership shows the welcome form, not a sign-in loop.
- [ ] Submitting the form creates a workspace and lands the user on its home page.
- [ ] The provisioning logic is shared between the JWT callback (first sign-in) and the welcome flow (recovery).
