Classes
struct	pulp::view::LayoutTreeSnapshotOptions
struct	pulp::view::LayoutTreeTolerance
struct	pulp::view::LayoutTreeDiff

Namespaces
namespace	pulp
namespace	pulp::view
	Hover-cursor tracking for platform window hosts.

Functions
std::string	pulp::view::dump_layout_tree (const View &root, const LayoutTreeSnapshotOptions &options={})
	Dump the current, already-laid-out View tree as deterministic JSON.
bool	pulp::view::layout_tree_snapshots_equivalent (std::string_view actual_json, std::string_view expected_json, const LayoutTreeTolerance &tolerance={}, LayoutTreeDiff *diff=nullptr)
	Compare two dump_layout_tree() JSON strings with the layout oracle rules: node kind/id/visibility/z-order/overflow must match exactly, numeric layout bounds must match exactly by default, and text-box dimensions allow a small tolerance for text measurement.
