Beginner / fast-path

Goal: get to a working Plan Card in ≤ 2 questions, then show defaults and let the user edit.

#	Question	Default if skipped
1	"What region? I can recommend if you're not sure."	eastus
2	"Linux or Windows? Default is Ubuntu 24.04."	Ubuntu2404 (Linux)

Silent defaults (show in Plan Card, don't ask)

• Size: Standard_D2s_v5 (2 vCPU / 8 GB)
• Auth: SSH key from ~/.ssh/id_rsa.pub (Linux) — read the file; ask only if missing
