C3D-0001 · TBC points yellow [TBC-YELLOW] error

Creates point style "TBC Yellow" with yellow (ACI 2) plan/model display colours and points the TBC point group style override at it. CogoPoint colour comes from the point style, not the layer.

C# payload

// Make the TBC points YELLOW.
//
// CogoPoints ignore their layer colour - the POINT STYLE controls the marker, and the TBC point
// group has IsPointStyleOverridden=True pointing at the "Test Pit" style, so that override is
// what is being displayed. Changing the layer would do nothing.
//
// Creates (or reuses) a point style "TBC Yellow", sets its plan + model display colours to
// yellow (ACI 2), and points the TBC group's style override at it. "Test Pit" is left alone -
// other groups (UTIL, GAS, WALL) use it too.
//
// API verified by reflecting AeccDbMgd:
//   PointStyleCollection.Add(string) -> ObjectId
//   PointStyle.GetDisplayStylePlan(PointDisplayStyleType) -> DisplayStyle { Color SET, Layer SET }
// Host owns Tx; host regens after commit.
