// Trading Terminal demo data for the read-only presentation account.
//
// This mirrors src/lib/trading/demoData.ts (the frontend's own, already-built
// "realistic trading demo" generator, which exists but is never invoked
// automatically — the project's "no seeded data" rule forbids that for real
// accounts). The backend cannot import frontend modules (separate TS
// projects, no shared path aliases), so the three accounts are reproduced
// here verbatim rather than duplicating the generation logic — this is data,
// not a second implementation of it. Keep both files in sync if either one
// changes; this file is only ever read by seed-demo-account.ts, on request,
// for one explicitly named account.
