/**
 * mcq-runner.css — Light theme for MCQ start screen + exam runner.
 *
 * ROOT CAUSE of "raw HTML" look: exam.css never defined .mcq-start-* rules,
 * and the runner shell used a dark palette (#0d1117) that fights the platform
 * light-theme standard. This file is loaded AFTER exam.css and overrides MCQ-
 * specific surfaces to a professional light SaaS look without rewriting coding
 * runner dark chrome shared in exam.css.
