The tmux statusline draws powerline/Nerd glyphs that default fonts lack,
so they render as blank/"?". tmux runs on every host (not just the Sway
ones), so install the font in the shared common-nixos module rather than
swaywm -- a future console-only or non-Sway host gets it too. The Mac
installs it via the Darwin config (/Library/Fonts). foot names it as its
main font (home/sway.nix).
On macOS, iTerm2's font is still a GUI setting: Settings -> Profiles ->
Text -> Font -> "JetBrainsMono Nerd Font".
