/* Urvalskalkyl — app styles.
 *
 * Mobile-first on a phone, desktop-first on a computer, decided by CSS media queries
 * so that resizing a window keeps working (app-ux-guide.md §3). No CSS framework, no
 * webfont, no external anything: the app ships a strict CSP with no off-origin request.
 *
 * Contrast: every text/background pair below is >= 4.5:1 in both colour schemes.
 * Nothing carries meaning by colour alone — every danger colour is paired with a word.
