The title, view buttons and origin sit in one 44 px band on the model. 부재 표시 is a collapsible panel on the left and 색 기준 (③ only) a collapsible panel on the right, both over the canvas, about 170 px wide, with 44 px touch targets. Below 600 px the band wraps and the panels fall below the model. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
