# this file configures preferences per program, without actually enabling any programs.
# the goal is to separate the place where we decide *what* to use (i.e. `sane.programs.firefox.enable = true` -- at the toplevel)
# from where we specific how that thing should behave *if* it's in use.

      # ways to enforce scaling:
      # - <https://wiki.archlinux.org/title/HiDPI>
      # - `swaymsg -- output DSI-1 scale 2.0`  (scales everything)
      # - `dconf write /org/gnome/desktop/interface/text-scaling-factor 2.0`  (scales ONLY TEXT)
      # - `GDK_DPI_SCALE=2.0`  (scales ONLY TEXT)
      #
      # application notes:
      # - cozy: in landscape, playback position is not visible unless scale <= 1.7
      #   - if in a tab, then scale 1.6 is the max
