/**
 * The ONE ANSI palette Vendo paints with, and the one rule for whether it
 * paints at all.
 *
 * Two surfaces need it — the CLI's rail renderer (`cli/pretty.ts`) and the boot
 * summary `createVendo` prints — and core is the only package both may import:
 * a block may not import `@vendoai/vendo` (scripts/dependency-guard.mjs), so a
 * palette living in the umbrella could never be shared downward.
 *
 * The MARKERS (◆ ◇ │ ✓ ⚠ ✖) are deliberately not here. They are layout, not
 * colour: each call site owns the ones its own block draws.
