Build-time accessibility contrast audit

vark build runs a WCAG color-contrast audit over the theme palette compiled from your theme.scss — light and dark — and reports every pair that lands below the level you asked for, so a regression shows up at build time instead of in a reader’s browser.

The audit is deliberately non-fatal: it warns and the build finishes, because a contrast miss is a design call to make on purpose, not a reason to block a deploy. It runs by default; a11y: false in aardvark.config.yaml silences it, and a11y: {contrastLevel: AAA} raises the bar from AA (4.5:1) to AAA (7:1).
