// Baut den Prüfstand: node scripts/workers-harness/build.mjs <outDir>
// entry.jsx -> harness.js + harness.css (esbuild, Entwicklungsmodus, damit StrictMode wie in der Entwicklung zweimal einhängt), dazu index.html.
// outDir muss ein neuer oder leerer Ordner unter dem Temp-Ordner (TMPDIR, sonst /tmp) oder unter .superpowers/ im Repo sein.
// Die Schrift /fonts/* bleibt außen vor: der Server von shot.cjs liefert sie aus public/fonts.
// Drei Module der App hängen an Appwrite (Anmeldung, Mitarbeiterliste, Sitzungs-JWT) und werden nur im Prüfstand ausgetauscht, damit die
// echte Seite WorkersPage (Reiter Hochhaus, Freigabe und Bot-Leads) samt PultList, ProspectPanel und BotLeadList ohne Netz läuft: AuthContext -> stub-auth.js,
// useEmployees -> stub-employees.js, workersClient -> stub-client.js. Am Quelltext der App ändert das nichts.
