# Local development only. Generates a fresh access token from the local
# Stalwart dev container (see docker-compose.yml) and writes it to
# .env.development.local (gitignored). Bash equivalent of dev-token.ps1, for
# non-Windows shells (and AI agents without PowerShell).
#
# Requires scripts/dev-server-init.sh to have been run once first (creates
# the "devadmin" account this script authenticates as — the
# STALWART_RECOVERY_ADMIN account is break-glass only and always issues
# fixed 1h tokens regardless of server config, so it can't honor a custom
# duration).
#
# Usage: dev-token.sh [duration_seconds] [api_base_url]
#   dev-token.sh            # 3 hour token (server default, see dev-server-init.sh)
#   dev-token.sh 1800       # 30 minute token
