When moving this part of the code to a dedicated function, the IDE
"helpfully" "fixed" the indentation, making the organization
of this part of the code less clear.

In the character sheet, this is an input field and is automatically tracked
thanks to flags.
Add an icon for the party sheet and the according CSS class.
