// Eigen-only type aliases. Include this instead of <reusex/types.hpp> when a
// translation unit needs only the linear-algebra helpers (no PCL point-cloud
// containers). Keeping the Eigen and PCL aliases separate avoids force-pulling
// the (heavy) PCL headers into TUs that never touch a point cloud.
