 *   sheet / canvas / subtle / inset  →  surface lo → hi, and the sunk well
 *   fg / muted / dim                 →  ink, ink2, ink3
 *   line                             →  the engraved rule
 * Green is intent (focus, selection, live), never a call to action; red is destructive only.
 *
 * The colorway follows the system unless <html data-mu-colorway="bone|graphite"> overrides it.
