# User onboarding: renders the user profile (user/USER.md) from the canon
# template. User name is REQUIRED; everything else is optional at this time
# (skillset is intended to be filled ongoing by agents in later layers).
#
# Usage:
#   scripts/onboard.sh                          # interactive prompts (TTY)
#   scripts/onboard.sh --name "Jason" [--timezone "Europe/Berlin"] [...]
#
# Fields: name (required), profession, marital-status, age, gender,
#         education, location, timezone, skillset, interests, hobbies, pets
#
# The rendered profile is dispatched to every agent launch. Re-running
# onboarding replaces the profile (the previous file is kept as .bak).
