Playbooky (novy nazev -> co dela):
- priprav-novy-server.yml (kompletni setup noveho serveru)
- nasad-sluzby.yml (nasadi Docker sluzby z docker-services/)
- aktualizuj-sluzby.yml (docker compose pull && up -d)
- zabezpec-server.yml (sysctl, auditd, unattended-upgrades)
- bootstrap-server.yml SMAZAN (duplicitni s priprav-novy-server)

Role (novy nazev -> co dela):
- zaklad (update + base baliky + timezone)
- uzivatel-deploy (vytvori deploy usera UID 1000)
- ssh-klice (authorized_keys deployment)
- docker (Docker Engine + Compose plugin) - ponechan anglicky (IT konvence)
- adresare (/home/deploy/{docker,scripts,backups,logs,...})
- firewall SMAZAN (nepouziva se)

Reference v playbooku aktualizovany na nove nazvy roli.
