The three state colours are DynamicColors on their own tonal palette now, built
exactly as Google builds error/on-error/error-container/on-error-container in both
specs, so the scheme's contrast level, dark tones, spec version and platform reach
them as they reach every other role; --harmonize (and a profile's harmonize) pulls
each source towards the seed, off by default. material:scheme also writes M3's
medium (0.5) and high (1.0) levels for both themes and every profile, keyed on
data-contrast and never on a media query, and --contrast now moves the standard
block alone. Scheme::load() takes the level; the mail theme stays on standard.
Plan: docs/plans/material-3-alignment.md, steps 6 and 7 (core C1, C2, C15).
