+ * DXF group codes used by AutoCAD for reading and writing DXF/DWG data.
+ *
+ * This enum mirrors Autodesk.AutoCAD.DatabaseServices.DxfCode exactly.
+ * Values indicate both semantic meaning and expected data type.
+ *
+ * @remarks
+ * - Group codes 0–9: string / symbol data
+ * - Group codes 10–59: floating-point values
+ * - Group codes 60–79: short integers
+ * - Group codes 90–99: 32-bit integers
+ * - Group codes 100–107: subclass / control strings
+ * - Group codes 300–369: strings / handles
+ * - Group codes 370–389: lineweight / plot style
+ * - Group codes 400+   : extended data (XData)
+ * - Negative values   : internal / structural markers
