# Tail logs from a service in either the Supabase or LiveKit compose stack.
#
# Usage:
#   ./scripts/prod/logs.sh <stack> [<service>] [<tail>]
#     stack   = supabase | livekit
#     service = (optional) single service, default = all
#     tail    = (optional) line count, default = 100
#
# Examples:
#   ./scripts/prod/logs.sh supabase             # all services
#   ./scripts/prod/logs.sh supabase auth        # just auth
#   ./scripts/prod/logs.sh supabase auth 300    # auth, last 300 lines
#   ./scripts/prod/logs.sh livekit livekit 200
