-     * SURFACE — Moonlit Serenity
-     * Barely-cool neutral (hue 215-232°, chroma 0.003-0.030).
-     * This is the "shiny serenity" — the surfaces feel like clean
-     * moonlit paper in light mode and a calm midnight sky in dark mode.
-     * The chroma is intentionally extremely low; it reads as neutral grey
-     * but with an imperceptible cool quality that lifts the whole palette.

-     * 50  → body-bg light:  nearly pure white, faintest cool whisper
-     * 950 → body-bg dark:   deep midnight slate with subtle cool depth
