All notable changes to this project will be documented in this file.

Added

• Initial Source SDK implementation that generates AES-256-CBC encrypted QR payloads.
• Source.instance.present(...) embeddable Widget to render encrypted QR codes.
• Automatic secure generation and platform secure storage of a 32-byte encryption key (source_encryption_key).
• Payload includes transaction and merchant objects. Merchant uses Source accountId.
• Helpers to decode payloads (decodePayload, decodePayloadWithMerchant) and payWithApi helper.
• README.md and INSTRUCTIONS.md documentation files.
