/* ============================================================
   Kids Kingdom - Swar Picture Quiz
   Image on the left (25%), 8 Devanagari letters on the right
   (75%, 4x2 grid) - pick the letter that starts the picture's
   word. All 10 questions shown in a list. Identical structure
   to alphabet-picture-quiz.css, with slightly smaller/flexible
   letter-button text to comfortably fit wider conjuncts like
   क्ष, त्र, ज्ञ, श्र.
   Reuses exam-btn/exam-score classes from addition-exam.css.
