/* ============================================================
   EduJA — Vocabulary Game (vocab.html / js/vocab.js)
   Reuses .assess-content/.assess-header/.assess-grid/.assess-card/
   .assess-start-btn/.assess-result-banner/.access-gate above and
   from css/style.css/css/assessment.css; this file only adds what's
   unique to the Flashcards flip card and the Matching Game grid.
   Launched as a Grade 7 pilot (2026-09), expanded to all seven
   grades (7-13) — see js/vocab.js. .vocab-pilot-note is now
   just the generic "nothing unlocked for your account" note style;
   kept the class name to avoid an unnecessary HTML/CSS rename.
