/**
 * Zero-UI "Command Compiler" personality (2026-06-05). Scoped to #mkt-zero-ui-lab.
 * A light editorial surface where a plain sentence compiles, in front of you,
 * into a governed tool-call (dark JSON editor pane) and a live result canvas.
 * Electric indigo/violet accent. Mixed light page + always-dark code inset →
 * the dark inset's fixed tints carry off-token-allow markers (inside braces).
 * Responsive-flow only.
