• Screen: SCR-PLY.04 — Quiz Start
• Use case: UC-PLY.02 — Take Quiz

Pre-attempt landing screen for a quiz_ref content item — shows quiz title, instructions, metadata (time limit, passing score, max attempts vs used), and the most recent completed attempt (if any) before the learner decides to start. If the learner has an in-progress attempt, the system bypasses this screen entirely and routes directly to the Quiz Player (AF-2A) — no Resume button is shown here. Renders inline within the SCR-PLY.01 viewer area; PLY sidebar and shell remain visible throughout.

1. Read-only mode (AF-2B): when attempts_used >= max_attempts, start_attempt is hidden and view_latest_result is shown instead. [SS-PLY.09]
2. Bilingual display (Lao/English) with Lao Unicode support across all regions. [SS-PLY.01, NFR-14]
3. attempts_used is fetched from the server at page load — client cache must not be used. [SS-PLY.04]
