Adaptive display and control geometry — surfaces are packed cells under a pure layout function, not free-floating windows. Hard monochrome chrome. Maximal utilization. M/G/S/MGS layer mask. Hash-verified Adapt.
No drag-pin desktop metaphor. Open tools become rectangles in a deterministic pack: focus gets the primary cell; remaining open surfaces fill the residual region as a grid. Utilization and waste are first-class metrics.
Layout = Pack(viewport, focusId, layerMask, mode, swarmPressure, panels)
