What is the default font in a modern SP Online document library?

Question

Formatting a column breaks the font style inheritance so for consistency I need to know exactly what font is used to replicate it. An inspection gives me this which doesn't look anything like the font style of other unformatted columns:
"font-family": "Segoe UI Segoe UI Web wf_segoe-ui_normal Helvetica Neue BBAlpha Sans S60 Sans Arial sans-serif"

Hi @matt howell ,

Segoe UI is the default font of SharePoint online.

As you can see it in my end:

{  
   "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",  
   "elmType": "a",  
   "txtContent": "@currentField",  
   "attributes": {  
      "target": "_blank"  
   },  
   "style": {  
     "font-family": "Segoe UI"  
   }  
}
