/*
 * Deliberately NOT built on Portal's `.es-*` design system — file 07 §6:
 * "deliberately not styled like either console... this is an exam-hall
 * screen, not a dashboard." No EduSphere branding, no color tokens shared
 * with the rest of the suite — a candidate sitting a formal, invigilated,
 * anonymized exam shouldn't be looking at a school-branded dashboard chrome.
 * Plain, high-contrast, large touch targets, nothing else on the page.
