+/**
+ * One-shot The Nook license Ed25519 keypair generator.
+ *
+ * Run with: bun scripts/generate-license-keys.ts
+ *
+ * Prints:
+ *   - The Ed25519 PRIVATE key as base64 PKCS8 DER  → NOOK_LICENSE_PRIVATE_KEY
+ *     (freno-dev env).
+ *   - The raw 32-byte Ed25519 public key (the X coordinate) as base64 SPKI DER
+ *     suffix → compiled into the Swift `LicenseVerifier.PublicKeyConstant`.
+ *
+ * The private key lives ONLY in env — never in git.
+ * Paste the public key into Sources/NookCore/Licensing/LicenseVerifier.swift
+ * (step 4 of the distribution plan) after running this once.
