/**
 * The two "draw less" space options and the virtual-wall rule (owner
 * 2026-08-05), plus the handle beads that came with them.
 *
 *   • «Скрыть декоративный слой» hides decor everywhere EXCEPT its own editor;
 *   • «Скрыть проёмы» hides doors/windows everywhere EXCEPT the plan editor,
 *     and does not touch what an opening MEANS (the light still gets through);
 *   • a space that does not draw room borders draws no dashed virtual walls
 *     in View; every editor still does, because the complete centreline span
 *     must remain visible while editing;
 *   • both switches survive a round trip through the dialog;
 *   • every corner handle paints a bead a quarter of its hit radius, and the
 *     hit radius itself is unchanged.
