// Reads the bot's IPC sock if available (live snapshot), else falls
// back to "what would the picker say given an empty inventory". The
// useful form is the live one.

// Usage:
//   node scripts/show-story.js            # live snapshot via IPC
//   node scripts/show-story.js --plain    # show static catalogue
