# demo.sh — watch a REAL migration land in your bgz project in ~30 seconds,
# WITHOUT needing a Jira / Linear / Shortcut account.
#
# It runs the real importer against a bundled CSV export
# (./examples/<source>-export.csv) via `bgz migrate <source> --file` — the exact
# same no-token path you'd use on your own export. First a `--dry-run` preview
# (nothing is written), then — on your OK — the real import.
#
# A live migration is one command straight from your tracker's API:
#
#     bgz migrate jira     --from URL --email EMAIL --token TOKEN --project PROJ
#     bgz migrate linear   --token KEY --team ENG
#     bgz migrate shortcut --token TOKEN --project "My Project"
#
# …or point --file at your own CSV export — no token needed.
#
# Usage:  ./demo.sh [jira|linear|shortcut] [--yes]
# Needs:  bgz (npm install -g buggazi) + logged in (bgz login).
