          this option independently — otherwise non-US users get the
          right layout in XWayland apps and the console but the US
          fallback inside native-Wayland apps.

        Gaming preset (home-side companion to nomarchy.system.gaming.enable).
        Adds a Hyprland window rule that fullscreens windows whose class
        matches steam_app_* — i.e. games launched through Steam — so they
        grab the whole screen instead of opening windowed. Set this to the
        same value as nomarchy.system.gaming.enable; the installer flips
        both when the Gaming profile is selected.

    accessibility = {

        Accessibility preset (home-side companion to
        nomarchy.system.accessibility.enable). Adjusts the Hyprland
        Wayland session in three ways: slows input.repeat_rate to 25
        (from 40) and input.repeat_delay to 1000 ms (from 600) so
        holding a key isn't a runaway machine-gun for users with
        low-mobility hands; binds SUPER+ALT+S to launch the Orca screen
        reader (the system preset already puts orca on PATH); and is
        the gate behind which a future high-contrast palette will hide.
        Set this to the same value as nomarchy.system.accessibility.enable.
