/*
 * Talking Time PupilTrackingCard — anonymised pre/post aggregates.
 *
 *   - aggregate counts, mean/median deltas, setting counts per
 *     filter combination (Req 48.4)
 *   - suppressed cells rendered as the literal text
 *     ``data suppressed for anonymity`` coming STRAIGHT from the
 *     backend (Req 48.5 + Property 8). This component MUST NOT
 *     derive the suppressed value from any other field and MUST
 *     NOT re-implement the k=5 suppression locally — it just
 *     displays what the backend sends.
 *   - Export PDF / CSV buttons hit ``/export.pdf`` and
 *     ``/export.csv`` endpoints which the browser saves via a
 *     Content-Disposition attachment header (Req 48.6)
 *
 * Scoped under .tt-area (Req 5.5).
