/* Heyming OS — embedded app surfaces (terminal, calculator) hosted inside .os-window-content.
 *
 * Brand-routed: the terminal fallback keeps a green-on-black identity by
 * routing through --success + --pure-black so the terminal still reads
 * as a terminal but the palette comes from /brand.css. The calculator
 * fallback uses brand surfaces / accent.
