Next steps:
  1. Terminal A:  ./serve.sh            (keep it running)
  2. ONE-TIME ARMING for unattended Claude runs:
       claude --dangerously-skip-permissions
     ...accept the warning, ask it to "call the magic-hour ping tool", quit.
  3. ./run.sh <fable|sol> <sunscreen|burger|codex-micro|bigben> [credits]
     (same shell as the API key export — Codex needs it for MCP auth)
