/*
 * A LIST-ROW disclosure. The trigger keeps the register's own rhythm — a 44px
 * press target on the row gutter — and its wash BLEEDS outward by a rung, so the
 * title sits on the container's left edge while the highlight still has room.
 *
 * The body is flush with the header BOX rather than with the title text: a
 * marked row's icon gutter pushes its title 28px in, and the panel belongs to
 * the section, not to the heading. An unmarked row draws no gutter, so its name
 * sits on the container's own left edge and the body lines up under it. No
 * tinted well — the chevron and the position already say "inside".
