Document Studio: one canvas for PDFs, templates, and direct send

Document Studio is becoming the room where documents actually get finished.

What's new#

• PDF tools live inside the Studio now, with guided tooltips — no more bouncing between the toolbox and your document.
• A modern, simplified start screen — recent work, templates, and a blank canvas, nothing else in your way.
• In-editor AI assist — rewrite, tighten, or extend any section without leaving the canvas.
• Direct send — when every signer on a template already has signature fields mapped, one click sends the envelope. No re-prepare step.
• Streaming chat persistence — AI conversations in the Studio survive reloads and network blips.

Removed#

The separate "Generate" route is gone; generation lives in the Studio composer where your document context already is.
