+ * PLACEHOLDER IMPLEMENTATION — READ BEFORE USE OR MODIFICATION.
+ *
+ * This class lays out views by direct, procedural arithmetic. It has no
+ * constraint solver. It cannot compress, expand, or negotiate space among
+ * views the way NSStackView does; it only places views at their existing
+ * frame size, in order, separated by fixed spacing.
+ *
+ * Known, accepted limitations:
+ *   - `distribution` is stored but has no effect on layout. Fill,
+ *     FillEqually, FillProportionally, and EqualSpacing are unimplemented.
+ *   - Center-gravity views are clamped against the Leading edge only; if
+ *     Leading + Center + Trailing content overflows the container, Center
+ *     views can overlap Trailing views instead of compressing.
+ *   - `visibilityPriority:forView:` only supports the two extreme values
+ *     (MustHold / NotVisible). Intermediate priorities are accepted but
+ *     have no defined effect.
+ *   - No guarantee is made of correctness beyond what a single manual
+ *     test (Tests/Manual/CPStackViewTest) exercises: orientation, the
+ *     three gravity areas, alignment switching, spacing, and hidden-view
+ *     detachment. Insertion, removal, custom spacing, and the CPCoding
+ *     archive path are implemented but not verified by that test.
+ *
+ * This exists to give AppKit a working CPStackView symbol now, not to be
+ * a durable design. It is expected to be replaced by a constraint-solver
+ * based implementation (Kiwi.js) when time permits. Do not build on its
+ * internal layout algorithm as if it were a stable foundation.
