You can still create a Code Card even if its programming language is not currently supported by the editor.
While creating a card, choose Other / unsupported language and enter the language name.
The card will use a plain-text fallback rather than full language-specific parsing or editor support.
Signed-in users can optionally indicate how important support for that language is by choosing a priority such as:
Low
Medium
High
Blocking
This helps Code Card prioritize future language support.
Unsupported-language cards can still be created, saved, organized, and published. They will display an Unsupported language label while the language remains outside the supported registry.
