Two mobile complaints, both in the editor/assistant context: - The global top bar (brand + account) sat above the editor's own garden-name strip — a whole banner of pure chrome over a full-screen canvas. Hide it on mobile in the editor (the same rationale that hides the bottom nav there) and fold a leaf/back affordance into the garden strip so there's still a way out. Desktop keeps the header. The editor's height band shrinks 8rem → 4rem on mobile to hand that space to the canvas; desktop stays 8rem since the header is still there. - The assistant (and journal/history) rendered inside the rail peek capped at max-h-[50vh]; after the tab bar, header and input, messages got ~200px. That cap is right for the inspector (read alongside the canvas) but not for a mode where reading/typing is the task. Panel modes now take a taller slice (78vh) via a `tall` prop; the inspector keeps the 50vh peek. Chat message spacing loosened gap-2 → gap-3.
