// ⚠️ IMPORTED HERE, NOT AT THE TOP, AND THAT IS LOAD-BEARING.
// A Workflow class must be EXPORTED FROM THE WORKER ENTRY for
// the runtime to bind it, so everything this module imports
// statically is evaluated on every cold start — including, via
// the email builder → branding service, the whole
// `@hono/zod-openapi` + Zod graph. That is a third of the
// worker's startup cost, paid by every request that is not a
// signing workflow, for code only this step uses.
//
// The class itself still extends WorkflowEntrypoint and is
// still exported eagerly: only the heavy subtree moved behind
// this await, so the runtime's contract is untouched.
