Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Zen mode may hide tab strips without closing views. Exiting restores prior strip visibility, preserves selected documents and reclaims only the configured strip height.

Why this case matters

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

One recorded failure
