// affirm.mjs — push an affirmation to a MacPal star.
//
// The star (macpal, default profile) polls /api/macpal-status?to=<recipient>
// every ~45s; this sets that message. Admin-only — uses @jeffrey's login token.
//
//   node macpal/affirm.mjs "proud of you 💛"            # → to=fia, production
//   node macpal/affirm.mjs "great work today ✨" --to fia
//   node macpal/affirm.mjs "testing" --local            # → https://localhost:8888
//   node macpal/affirm.mjs --clear --to fia              # blank the caption
//
// The chime that plays when the message changes is programmable — a named macOS
// system sound (Glass, Tink, Pop, Bottle, Hero, Submarine, Ping…) at --volume 0–1:
//
//   node macpal/affirm.mjs "ta-da ✨" --sound Hero --volume 0.5
//
// Playlists rotate server-side (survives this machine sleeping) — each quoted
// argument is one message, cycling every --every seconds (default 120):
//
//   node macpal/affirm.mjs --playlist "it's good to be calm!" "i love you!" --every 60
//
// Auth: reads ~/.ac-token (run `node tezos/ac-login.mjs` once to create it).
