Implement a workflow: <name>

Steps (in order):

1. <step> — route <…>, inputs <…>, validation <…>, primary action <…>
2. <step> — …
   Entry point: <where the user starts>
   Success end state: <where they land + what record(s) get created/updated>
   Back / cancel: <how each step handles going back and cancelling>
   Errors: <inline validation + failure handling per step>
   Data model: <the record(s) + fields the flow produces>
   Building blocks: <RecordForm | Dialog | AuthCard | a stepper (Steps) — per step>

Test scenarios (happy / unhappy) — generate the real cases from the steps
above; this is only the shape:
TC-1 Complete all steps with valid input -> success end state reached
TC-2 Step N invalid input -> inline validation, blocked
TC-3 Back from step N -> previous step, input preserved
TC-4 Cancel mid-flow -> returns to entry, nothing created
TC-5 API failure at submit -> error shown, can retry
TC-6 Refresh mid-flow (if persisted) -> progress restored

Done when: each step has loading/error/success, validation (Zod), the scenarios
above pass, tokens, light + dark, a11y, lint + types + build pass.
