GameWindow.OnRender: when clipRoot != null, run only InteriorRenderer.DrawInside
(per-cell shells + per-cell objects + live-dynamics); the global entity pass +
global shell pass are no longer issued indoors. Outdoor scenery drawn clipped to
the doorway (after terrain, before the Z-clear). Outdoor root path unchanged.
pvFrame hoisted so the splice reads OrderedVisibleCells; per-frame 3-bucket
partition built on the indoor root. Retail RenderNormalMode @ 0x453aa0.
InteriorRenderer amended with a DrawableCells membership filter (an IsNothingVisible
cell can be in OrderedVisibleCells but absent from CellIdToSlot — iterate for ORDER,
filter for membership; matches the old envCellShellFilter set exactly).
Build green, 174/174 App tests pass.

Per-cell flood: closest-first over OrderedVisibleCells, per cell draws the closed
shell (EnvCellRenderer.Render(pass,{cellId})) + that cell's objects, then live-
dynamics unclipped, then transparent shells. Reuses the existing dispatcher Draw
per cell (safe to call N x/frame; only diagnostic GPU-timing miscounts). Caller
owns the landscape-through-door + Z-clear. Not yet wired (Task 3).
