Styles and themes

Fifteen styles — ten flat and five gradient — and the contrast tests each has to clear, including bg-on-accent for the CTA block.

Theme { bg, fg, accent, muted, displayFont?, bodyFont?, bgGradient? }

What the tests enforce

Per style: fg/bg ≥ 4.5:1, muted/bg ≥ 3:1, accent/bg ≥ 3:1, and bg-on-accent ≥ 3:1 — because the CTA block prints theme.bg text on theme.accent.

Gradient styles are additionally checked against every stop, not just the first: contrast against theme.bg only checks one end of a ramp that text sits across the whole of. That test caught two real failures during development.
