▸ Sparkle appcast (TODO):
  1. Sign the update:  ./bin/sign_update dist/GrammaGem-<ver>.dmg
     (Sparkle's sign_update tool, using your EdDSA private key)
  2. Add an <item> to appcast.xml with the version, URL (GitHub Releases asset),
     length, and sparkle:edSignature.
  3. Upload the DMG + appcast.xml to a GitHub Release.
  The app's SUFeedURL points at the raw appcast.xml on GitHub — $0 hosting.

▸ Distribution touchpoints (all $0 marginal cost):
  - Model weights:  Hugging Face CDN
  - Updates:        GitHub Releases + Sparkle
  - Licensing:      Lemon Squeezy License API (% per sale only)
