Case contract

Vertical tab strips consume pane width rather than height, reserve group-header rows, size scroll content from row heights and keep close buttons aligned to the strip trailing edge.

Why this case matters

Offline tab/panel workspace behavior; no browser or desktop framework is emulated.
