/**
 * Section configuration — the only real difference between the poetry site
 * at / and the prose site at /mer-vi.
 *
 * Both used to be complete copies of every page. They differed in exactly two
 * ways: the genre they query for, and a handful of words (Poet/Writer,
 * לידער/דערצײלונגען). Everything else was duplicated, which meant every fix —
 * including the SQL injection and the graph.php command injection — had to be
 * made twice, and in practice sometimes wasn't.
 *
 * A page under /mer-vi sets $GENRE = 'story' and then includes the shared page
 * from the root. URLs are unchanged: /mer-vi/poem.php?poem=x still works.
