After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online xdeck is error-free.
• brew style --fix xdeck reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new xdeck worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask xdeck worked successfully.
• brew uninstall --cask xdeck worked successfully.

• AI was used to generate or assist with generating this PR. Claude Code was used to generate the cask formula and run the audit/style checks. The install and uninstall were verified on the author's machine.
