Dock
Dock
A window docked at the foot of the screen, beside the page and not over it: nothing dims, nothing waits, the page stays usable. Its header folds it to its title and back. It takes a page the server renders — `target: 'dock'` — or what a script shows there, like a modal and a panel.
A page loaded in a dock (`button_target(…, 'dock')`). Open both: they stand side by side.

What a script shows itself — `showInTarget(app, target, { title, body, actions })` — in a modal, a panel or a dock: the same shell as a page's, drawn in the browser.
