REWRITE RULES

       rewrite is an object where keys are regular expressions and values are rewrite rules if
       the expression matches. Rules may contain references to captures of the expression.

       Regular expression and replacement follow ECMA-script rules.

       If no expression matches, the title is left unchanged.

       Invalid expressions (e.g., mismatched parentheses) are skipped.

                     "(.*) - Mozilla Firefox": "🌎 $1",
                     "(.*) - zsh": "> [$1]"
                }
           }

       •   #window
       •   window#waybar.empty #window When no windows are on the workspace

       •   window#waybar.empty When no windows are in the workspace
       •   window#waybar.solo When only one window is on the workspace
       •   window#waybar.<app-id> Where app-id is the app ID of the only window on the workspace
