Approximates Material 3 tonal palettes for the four key roles. Tones 0 (black) → 100 (white) map via a smoothstep curve to HSL lightness — a rough perceptual fit that intentionally avoids the ~50 KB material-color-utilities HCT library. For pixel-perfect M3, generate via that package server-side.
Generate a Material Design 3 tonal palette from a single source color. Outputs primary, secondary, tertiary, and neutral tones.
