═══ Workload heatmap (Încărcare STO) ═══
- /app/workload custom Page (group Analiză)
- Săptămână (Lu-Du) × posturi → matrice ore programate
- Heatmap colorat: verde→galben→roșu pe ratio capacity (10h/zi)
- Navigare săpt anterior/curent/următor
- Programări fără pod → row '— fără pod —' separat

═══ Site PSauto (landing public) ═══
- / pe tenant subdomain → resources/views/site/landing.blade.php
- Hero cu logo + nume + slogan; gradient theme color
- Servicii (din settings.services) — grid card-uri
- Locație/contact + program lucru standardizat
- Mărci suportate (din settings.cars)
- CTA: phone + email
