Quarto – Document Language is related but different.

R package for this, but R: ropensci-review-tools/babelquarto: Renders a Multilingual Quarto Project (Book or Website)

Mario Angst - A multi-language (German/ English) Quarto website

• Profiles + visible-when — all langs in one file, looks kinda ugly but why not…
• Quarto – Project Profiles

oooo12 - Multi-language Blog with Quarto - Guide profiles as well.

Approach for now — write them in separate files, and optionally at some point include them in the visible-when option?..
