// Shared structural style tokens for the shell. Color is the palette
// singleton; Style holds the *shape* and *focus-affordance* tokens that
// every panel surface and qs.Ui component should bind to so they stay
// in sync as the user toggles round/sharp corners or as themes change.
//
// `cornerRadius` mirrors Hyprland's `decoration:rounding`. Themes ship
// their own rounding via theme/hyprland.lua; the user toggle via
// `omarchy style corners <round|sharp>` flips Hyprland's flag file
// and Hyprland's auto-reload pushes the new value out. The shell picks
// up the change here by re-running `hyprctl getoption` whenever either
// of those input files changes.
//
// Single source of truth lives in Hyprland; the shell follows. That
// means a theme that ships `rounding = 10` gives us 10px panels by
// default, and the round/sharp user toggle still works on top of it.
