/*
 * hosted·ai files: base design system. Tokens, type and shared components, used by
 * every page (dashboard, sign-in, landing, public list, error pages). Page-specific
 * layout lives in its own sheet (dashboard.css, pages.css). See DESIGN.md.
 *
 * The pages send a strict CSP (style-src 'self'): no <style> blocks and no style=""
 * attributes anywhere. Everything visual lives in these sheets. Scripts may set
 * geometry through CSSOM (el.style.width = ...), which CSP allows.
 *
 * Brand: hosted·ai files (logo kit: ~/dev/files-logo/kit, guidelines.md). Violet
 * #503AA8 is the one accent. It is used for the logo dots, the primary button, links
 * and the selected state. Coral #FF8B53 is a mark
 * only: the logo's accent dot and the "starred" star. It is never used for text.
 * The neutrals are warm, built on #F7F6F4 / #211F1D in light mode and #141312 /
 * #F3F1EC in dark mode.
 *
 * Contrast, checked against the surface each token sits on:
 *   text 15:1, text-2 7.3:1, text-3 5.1:1 (light) / 6.6:1 (dark);
 *   accent-text 8.4:1 (light) / 6.0:1 (dark);
 *   white on accent-strong 8.1:1 (light) / 5.1:1 (dark);
 *   border-input and focus both clear 3:1.
 *
 * Dark mode is declared twice: once under prefers-color-scheme (the OS setting,
 * unless the viewer chose light) and once under [data-theme="dark"] (the toggle).
 *
 * Type: Manrope (variable, 200-800, OFL; fonts/OFL-Manrope.txt), self-hosted as
 * Google's latin + latin-ext subsets. Body text uses proportional figures. Tables
 * and figure columns set tabular-nums.
