I see quarto::quarto_render() has a cache option but it's only for code chunks. 🤔

maybe freezing

with the exception that we always want to re-render the doc where we read info from Airtable/GitHub (reviewers, editors)

freeze not a good fit, it's for computation.

Now, the problem is, everything is intertwined: if I change a chapter title, the TOC needs to be updated everywhere.

maybe I could implement a function for rendering the currently opened file. 🤔
