OG-Image: Next.js 16 / Satori verlangt 'display: flex' (oder contents/none) auf jedem Container-Div mit mehreren Children. Vorher crashte das Image-Rendering mit 'Expected <div> to have explicit display: ...'. Jetzt: alle Container haben display: flex, Image rendert sauber. Build-Hash: Dockerfile hat die ENV-Vars NEXT_PUBLIC_BUILD_HASH/DATE zwar als ENV deklariert, aber sie landeten nicht im finalen Image (ENV in Build-Stage verschwindet im Standalone-Build). Fix: schreibe die Werte in eine .env.production.local vor dem Build — Next.js liest die in der Build-Phase, bakt sie in den Client/Server-Code, und der Standalone-Output enthält sie.
