Three related "fill the available height" layout fixes to the connected screens:
- Tools & Prompts sidebars: replace the fixed magic max-height on ToolControls/
PromptControls with the Resources pattern — sidebar Card `variant="sidebar"`
(full-height flex column) + `Stack flex={1} mih={0}` + a flex-filling
ScrollArea — so the list runs to the bottom of the card before scrolling.
- Logs/Console/Protocol/Network standalone screens: only override ScreenLayout
`h` when embedded. Passing `h={undefined}` clobbered the default
`h: calc(100dvh - header)` (withProps plain-spreads), collapsing an empty
screen to its controls' height. Also center the Network/Protocol empty states.
- Tools placeholder: render the "Select a tool" empty state in a full-height
`DetailCard flex={1}` (like Prompts/Resources) instead of the content-sized
preview card, so it fills the pane.
