I try to comply to the existing style guide https://www.doubleslash.style/

Please add this issue as sub issue to #1257 [Feature Request] Add more customization to styles

Describe the solution you'd like
In my likec4.config.json I try to define a color "#00A5E1" for the border using "stroke"
"system": { "elements": { "fill": "#FFFFFF", "stroke": "#00A5E1", "hiContrast": "#000000", "loContrast": "#000000", }, "relationships": { "line": "#6D6D6D", "label": "#000000", "labelBg": "none" } }

However this border is only shown as soon as the element is selected:

Selection

I would like to have the possibility to define a border color permanently used in all representations of an element.
