/*
 * The tafsir block (LN8): stored verses, then the stored Ma'arif al-Qur'an commentary in a closed panel that opens in
 * place as a reading sheet: a comfortable column, a bar of how far you have read, topics to jump to, and the passage
 * kept inside its own scroll so a long commentary never pushes the lesson's buttons away. Dressed by the world's colours
 * and the look; light and dark come from Learn's own variables. The commentary is English (left to right) on every
 * site; the Arabic it quotes is marked and set in the Arabic font.
