/**
 * OSC 11 terminal-background probe: the query sequence and the reply parser.
 *
 * Terminals answer `ESC ] 11 ; ? BEL` with their default background color,
 * which lets full-screen views derive elevated surfaces from the user's own
 * palette instead of hardcoding one. The reply arrives on stdin as an OSC
 * sequence (tokenized by `nextKey`); terminals that don't support the query
 * simply never answer, so callers must treat the color as optional.
