/*
 * voter2027.fr — base design tokens and shared chrome (header, footer, buttons, cards, forms,
 * score badges). Public and admin builders add public.css / admin.css alongside this — this file
 * is the shared vocabulary, not the whole look of any one page.
 *
 * Design brief (SPEC.md "Design"): calm, civic, trustworthy, not partisan. No party colours. One
 * neutral accent. Generous line height. System font stack. Large tap targets. Score badges use
 * shape + word, never colour alone. Light and dark via prefers-color-scheme. Mobile first
 * (375px), then desktop.
