+Version 0.1.4 completes the narrowly scoped public-HTML footer compatibility layer by normalizing the known legacy Brizy footer variants to the current operator, KVK, copyright, trademark, and tagline text. It does not modify stored page, product, Tokenomics, payment, or authentication data. Version 0.1.3 introduced the compatibility layer. Version 0.1.2 adds a normal WordPress browser authorization handler for XUMM-authenticated sessions while retaining the REST exchange contract. Version 0.1.1 aligned state validation with the backend's signed v1 protocol
 (timestamp, nonce, and HMAC-SHA256 signature) and supports an exact allowlisted
 external callback without requiring a separate WordPress redirect-host filter.
