Purpose

To implement the rebranding from "CryptoX" to "Concordium Wallet" across the documentation.
The changes update placeholder definitions, rename files with cryptox in URLs, and configure redirects to maintain backward compatibility for external links.

Changes

Text content updates:

• Updated main placeholder in variables.rst from "CryptoX Concordium Wallet" to "Concordium Wallet"
• Created cryptox-legacy placeholder for historical accuracy in release notes
• Fixed missing variables.rst includes in files where placeholders weren't rendering
• Replaced hardcoded "CryptoX" references with appropriate placeholders where found

File renaming and URL structure:

• Renamed cryptox-faq.rst → concordium-wallet-faq.rst
• Renamed setup-cryptox-wallet.rst → setup-concordium-wallet.rst
• Renamed cryptox-terms.rst → concordium-wallet-terms.rst
• Updated all internal reference anchors (_cryptox-faq → _concordium-wallet-faq, etc.)
• Fixed broken internal links in 4 files that referenced the old anchors

Redirect configuration:

• Added three URL redirects in conf.py to maintain backward compatibility

Release notes:

• Historical releases now use cryptox-legacy placeholder to maintain accurate branding
• Future releases will use updated cryptox placeholder

Screen shots:
Removed screen shots showing CryptoX, including a few more redundant screen shots, in the following files - and made a few text updates to make the setup and recovery flow look less complicated:

• setup-concordium-wallet.rst
• recovery.rst

Note: Download path changes are pending and must be addressed in follow-up work.
