/**
 * Special character picker data (Direction B scope, per the owner-approved
 * proposal - see the "Formula Library & Special Character Picker" scoping
 * artifact): six categories, ~200 characters total. Unlike the formula
 * library, this set is drawn from standardized Unicode blocks, so "cover
 * this category" is a genuinely completable goal, not an open-ended one.
 *
 * Every entry inserts as plain text (see `insertSpecialCharacter` in
 * CanonicalAuthorityEditor.tsx) - special characters are ordinary
 * characters, never schema-level atoms.
