Part 2 of the ideas from 2026-10-04.

• The live screen sits on a desk of the bot's color (browser-stage.css): the color mixed with the panel, soft in light, deep in dark, with the page as a window with a shadow. Closed, the desk fades with the last picture.
• A pill hangs from the desk's edge and says who is in control: the mascot and "Scout is in control" with Take control, or "You are in control" (accent border) with Done, give it back to Scout. It drops in again when control changes hands.
• Under it: what the bot just did, Sign in in a window, and How it works, folded, with the explanation that used to sit there in full (as the owner asked: who knows it should not keep it on screen).
• The owner's lines (click to type, the bot waits, the tab it goes on in) moved from the bar above the screen to under the pill.
• In a narrow panel the pill's phrase leaves the screen (kept for screen readers) and the button says the rest.
• The page room now subtracts the desk and the pill (spec 21.8); spec 21.8, 21.10 and 21.11 updated.

Test plan

• pnpm check (pill states in hands.test.tsx, folded help in window.test.tsx, new room size in browser.test.tsx)
• Preview: Scout's browser in dark, light, wide and narrow; take and give back
• Real app: take control of a bot's browser and give it back; the page keeps its size
