/*
Note: This theme uses the Roboto font family, which it imports from Google
  Fonts to ensure consistent weighting in addition to availability. While
  you can use a local installation of Roboto, this is generally not 
  recommended since the weighting will likely be wrong (probably too
  light). OTOH, importing from Google Fonts can cause some issues in
  certain secure environments due the external CDN (see:
  https://github.com/grantmcdermott/quarto-revealjs-clean/issues/7). If
  that's the case for you, simply comment out the `@import url(...)` line
  below and it will default for the default Sans Serif font on your system
  (e.g., Helvetica on a Mac). Circling back to the earlier point about
  preserving consistent font weights, you may also wish to remove "Roboto"
  from the choice set if the family is installed locally.
