/*
 * exam-paper.css — makes the practice-exam pages look like a real NCEA exam paper.
 *
 * Loaded ONLY by the prediction-exam-*.html pages, and every rule is scoped to
 * body.exam-paper, because .question-box is shared with every topic bank on the
 * site. Nothing here changes the page's markup or behaviour except the formula
 * panel, which main.js builds.
 *
 * What it borrows from the real papers: Times New Roman question text, Arial
 * headings / cover / tables, the cover's layout (spaced standard number, big
 * level number, grey title band, criteria table), and the dotted margin strip,
 * which here holds each question's tools so they are always visible (hover
 * does not exist on phones). No NZQA branding.
 *
 * ⚠ Targets the DOM AFTER main.js has run: groupQuestionHeaders() prepends a
 * .question-header (grade tag + empty h4 + time display) to each part, and
 * fetchAndDisplayPredictionExam() adds .mark-scheme-container blocks, the
 * marking-schedule controls and the cut scores. If the API is unreachable the
 * server-rendered questions stay (bare .grade-tag, no header) and still style.
 *
 * Each page sets its own footer line: style="--exam-footer: '...'" on <body>.
