-- Usable window rect for mobile chrome (notch / Dynamic Island / home
-- indicator / Android display cutouts).  Wraps love.window.getSafeArea when
-- the engine provides it; otherwise the full graphics window.
--
-- Desktop and headless stubs return the full window, so callers can always
-- layout against this rect without platform branches.  Interactive chrome
-- (touch overlay, launcher) should prefer this over getDimensions; the game
-- canvas may still letterbox into the full framebuffer for immersion.
