Motivation

In rustc, we disable trace and debug logging by default for performance reasons, using the max_level_info feature. This is very confusing to new contributors: they add debug!("x") to the code and run RUSTC_LOG=debug rustc,

Our docs look good when viewed from Dark Reader Firefox plugin, but unfortunately without it they look quite bright. We should somehow make paradox-material-theme darker to by default.
