/* bisestats result converter — the BISE Results Observatory design system.
 *
 * The tokens, radii and component shapes are lifted from the main site
 * (app/globals.css and app/page.tsx on the site's `main` branch) so the two read
 * as one product: the same navy hero and sticky header, the same teal eyebrow
 * labels over tight-tracked headings, the same white cards on the #f4f7f6
 * ground with #dfe8e5 borders.
 *
 * The site builds these from Tailwind utilities. This app is served by a small
 * Python process with no build step, so they are written out as classes here.
