Composite-pose chrome layout, composite-pose->draft, and
composite-draft->plan. Pure data-side: shared-scale reconciliation,
chrome geometry computation, per-leaf opt adjustment. The
plan-to-membrane rendering for composites lives in
render/composite.clj, keeping this namespace free of membrane
dependencies.
Shared scales: the pose stage says which cells share an axis
(impl.pose/shared-axis-groups), and composite-draft->plan measures
what those cells draw, pools it, and plans each with the pooled
extent.
When the composite root carries a legend-producing mapping (:color/:size/:alpha), the chrome reserves a strip on the right of the grid; the per-leaf opts get :suppress-legend true so each cell hides its own legend, and the rendering side (render/ composite.clj) draws ONE shared legend in the reserved strip.

(composite-draft->plan composite-draft)Convert a CompositeDraft into a CompositePlan. Per sub-draft, this calls draft->plan to produce a leaf plan and wraps it with its rect and path in :sub-plots. The shared-legend spec is computed once from a representative leaf draft (eliminating the rep-leaf-plan N+1 issue from the round-2 internals review).

(composite-pose->draft composite)Resolve a composite pose into a CompositeDraft
(composite-pose->draft*), first sizing it where it pins its panels.
:panel-width and :panel-height on a composite pin the panels of
its columns and rows, as they pin a single plot's panel: a number for
every column (row), a vector for each. They are the composite's
column (row) weights, and its width (height) is worked out from
them, as a single plot's is: the composite is planned once at its
given size to measure what its labels, strips and legend take, and
that room plus the pinned panels is its size. No cell reads them.
