Ask on the left. Watch it build on the right.
Studio is the Shell chat column at full-page scale — same rail, same composer, same cube-as-send, same UI glyph family. The difference is that chat fills the surface (there's no "main" behind it), and an asset canvas opens alongside when the conversation focuses something buildable — a figment running live, a workflow draft, a document, any node from the Objects map. A 2px kind-color underline in the canvas panel header carries identity through the whole view, so you always know what you're looking at. Think of Studio as the focused mode of the same instrument — the chat column expanded until it is the room.
Canvas is closed by default when the thread is blank — Studio's first move is an invitation, not a layout. The rail + chat column is the entire surface: a single bold What do you want to build? and four suggestions sized for one glance, with the same composer you'd see in the chat column — input row up top, + and cube-send on the action row beneath. The cube is in Ghost at rest because nothing has been asked yet; typing nudges it to Step, sending flips it through Uplink into Facet.
When the agent focuses an asset — a figment, workflow, or document — the canvas slides open on the right. The 2px kind underline in the panel header is identity's signature: figment blue here. The divider between chat and canvas is draggable (persisted per user); fullscreen lifts the canvas over everything.
