Follow-through on the canonical control set we shipped in early June. Now every button, chip, badge, tab switcher, and copy-confirm pill in the app, across Admin, Settings, artifact views, and the misc corners, sits on the canonical atoms. Same behavior, same visual, same focus, everywhere. The atoms themselves picked up the last variants they needed: a success button style, a danger icon button, a media size, a block layout mode, and a dark-chrome mode for dark-surface panels.
