/**
 * Typed API client (design D12).
 *
 * Types come from `schema.d.ts`, which is generated from the API's OpenAPI document — do
 * not hand-write request or response types anywhere in the frontend. If a Pydantic model
 * changes, this file's consumers stop compiling, which is the point.
 *
 * Server-side calls must forward the session cookie explicitly: Next.js server components
 * do not carry browser cookies automatically.
