// The shortcut list is generated from `hyprctl binds -j` rather than typed out
// here. The previous version was a hand-maintained array of nineteen entries
// against a real keymap of a hundred and thirteen: it could not show the rest,
// and it went stale the moment a bind changed. Every bind now carries its own
// description in hypr/keybinds.lua, and this page just groups and renders them.
//
// The hardware settings above the list are real controls. Keyboard layout,
// repeat behaviour, and pointer response are Hyprland's, so Panama owns them;
// device-specific configuration stays with GNOME.
