// ============================================================
// SHARED TYPES — consumed by both server (src/routes/*.ts) and
// client (client/src/*). A response-shape change here breaks the
// build on both sides until they agree.
//
// This is the single most important file in the TypeScript
// migration. Three of the bugs we hit before this point were
// response-shape mismatches (refine returned `content` vs
// `refined`, sick-visit endpoint path mismatch, hospital-course
// key mismatch). Typing the wire protocol makes them compile-time
// errors.
//
// Keep this file strictly about wire protocol — no DB row shapes,
// no server-internal helpers. Anything that crosses the network.
// ============================================================

// ── Envelope ─────────────────────────────────────────────────
// Every route returns either `{success: true, ...extraFields}` or
// `{success: false, error: string}`. The generic `T` is the shape
// of the extra fields on success. Client code does:
//   const r: ApiResponse<HpiOk> = await fetch(...).then(r => r.json());
//   if (r.success) console.log(r.hpi);
//   else           showToast(r.error);
