/**
 * Amber monochrome PC monitor look (think IBM 5151 / Hercules).
 *
 * Ships as a parameter-only set - the underlying colors stay full-RGB until
 * the {@link MonochromeQuantize} effect lands (tracked in
 * [VV-479](https://linear.app/vancura/issue/VV-479/monochrome-re-quantization-display-effect)).
 * For now this preset gives you the *feel* (CRT curvature + scanlines +
 * vignette + warm-tinted bloom) without the actual amber re-quantization.
 *
 * @returns Array of pre-configured display-tier effects.
