@SamyPesse Probably not the sexiest approach, but this way we can preserve the initial HTML (desktop TOC) and switch to the Sheet TOC for mobile, so no duplicate

I’m not a big fan of relying on useIsMobile, but given that we’re passing a context props (not serializable) to a lot of components, it’s tricky to implement a clean client-side solution without breaking things

I still think it's a good improvement and it won't change anything on desktop
