/*
 * SurveyFunnel design system: "Grounded + SurveyFunnel brand" (approved 2026-10-03).
 * Reference: DESIGN.md (tokens, components, usage rules).
 *
 * Order: tokens -> dark tokens -> accent-derived tokens -> base -> components
 * -> admin shell -> respondent -> marketing -> error page.
 *
 * Sage ground, ink text, white cards with soft radii; one accent (SurveyFunnel
 * blue) for primary actions, progress and the first score band. Display face
 * Fraunces (headlines, big figures, monograms); body and UI Source Sans 3; the
 * block wordmark is Saira Condensed. Fonts are self-hosted (/static/fonts/fonts.css, src/lib/fonts.ts)
 * with system fallbacks.
 *
 * Light + calm dark (prefers-color-scheme, or forced with html[data-theme]).
 * Contrast: text pairs meet WCAG 2.2 AA (4.5:1), focus rings and input borders 3:1.
 * Class prefix sf-. Respondent themes override --sf-brand / --sf-bg / --sf-text /
 * --sf-radius on <body> (src/ui/layouts.tsx themeStyle); a custom brand adds
 * body.sf-brand-custom, which re-derives the accent tints from it.
