AI Explanation:
- The script auto-executes on DOMContentLoaded (or immediately if DOM already loaded).
- It builds a Tracker closure that manages session state: start time, history array, items map, and pending payload queue.
- Items are inferred from text inputs and elements with data-question-id (or id/name/placeholder). If elements include data-correct or data-expected, those are parsed (supports JSON arrays) so the tracker can evaluate correctness.
- Event listeners:
  - focus on inputs => records input_focus with q, value, expected, marks.
  - blur on inputs => records input_blur, sets userSelection, attempts evaluation and records correct/marks if possible.
  - input events and paste => records input and input_paste events, updates item.userSelection, evaluates correctness.
  - keydown => increments a keystroke counter per input and periodically emits key_activity history entries (every 10 keystrokes).
  - form submit => records each form field as form_field_submit and an overall form_submit event.
  - click listeners on play/pause controls and a heuristic global click handler to record play/pause events.
  - MutationObservers watch elements with data-score/data-max and data-state (or common classes) and record score_update and game_state_change history entries when those elements change.
  - Window-level listener for custom 'gameStateChange' events is added to capture out-of-band game state changes.
- The tracker aggregates quiz state (attempted, correct, total, items) and computes score and max by summing item marks and maxMarks. If score elements exist with explicit data-score/data-max, they are also recorded as history entries.
- All transmissions to the learning system are done via window.storeState(payload). The script never constructs raw xAPI statements and never performs network calls. If window.storeState is not yet available, payloads are queued and flushPending retries until storeState appears (bounded by retry limits).
- The payload matches the SLS DATA CONTRACT shape exactly: top-level score, max, feedback, reason, quiz (with attempted, correct, total, points, items), and a history array of recent events with t, type, q, value, expected, correct, marks.
- A heartbeat timer periodically emits 'heartbeat' payloads, and a final 'session_end' payload is attempted on beforeunload.
- The tracker exposes a window.__SLS_TRACKER__ object (non-enumerable where supported) so host code can register external items (SLS interactive response parameters) by calling __SLS_TRACKER__.registerExternalItem({id, question, correctOption, maxMarks}).
