/* ========================================================================== y2-tokens.css — design tokens + self-hosted faces Redesign Phase 1. Reference render: /design-system.html -------------------------------------------------------------------------- This file emits NO visual rules. Only @font-face and custom properties on :root. Linking it into an existing page cannot change that page's appearance — which is what keeps the "zero style regressions" guarantee structural rather than a matter of spot-checking. Every colour pairing below carries its measured WCAG 2.1 contrast ratio. Those numbers are computed, not estimated. Re-measure before changing a hex. ========================================================================== */ /* -------------------------------------------------------------------------- FACES — self-hosted, variable, latin + latin-ext Both families are SIL Open Font License 1.1; the license texts ship alongside the binaries in /assets/fonts/.
