/* Minimal styles for the /surface/ page chrome (header + footer + lang switch).
 * Deliberately NOT the full site style.css: that file has a global `*` reset
 * and `h1,h2 { font-family: Playfair }` which bleed into and break the
 * diagnostic result screen. Here box-sizing is scoped to .header/.footer only,
 * so the diagnostic (in <main>) renders exactly as designed in isolation.
 * Keep header/footer rules in sync with css/style.css if those change. */
