/**
 * 共通 А–Я 表現索引 — Idioms & Collocations Index
 *
 * One shared alphabetical index over CAT [2-3-1-3] + [2-3-1-5]. The control
 * band (type filter / meaning-colour legend / alphabet) is the same band the
 * hub previews in its 共通 А–Я 表現索引 section, so the two must stay visually
 * identical — the shared rules are duplicated in hubs/idioms-collocations-hub.css
 * under .idmhub-index-* names.
 *
 * Per the special-page background contract this file sets no body background.
