"""PromptLedger Verifiable Provenance and Licensing (MVP core)

Lightweight in-process ledger core with:
- LocalProvenanceBlock: a single creative step with metadata
- MerkleAuditLog: tamper-evident log of blocks
- DeltaSync: compute simple deltas between two logs
- Adapters: Blender and Figma sample emitters

Note: This is a minimal MVP to bootstrap architecture; extend with real crypto
signatures, DID-based identities, and cross-tool adapters in subsequent tasks.
