+====== Programmatically Creating Complex SecsFormat00 Objects from Java Arrays ======
+===== 🧩 Convert Mixed-Type Nested Arrays: sf00FromNested(Object data) =====
 Recursively converts a nested ''Object'' array into a hierarchical SECS structure, inferring SECS types based on the Java type of each leaf element.
 You may use this method when your structure may contain integers, floats, doubles, longs, or strings. Each array level becomes a ''SecsFormat00''.

-<code java>
+==== Example method ====
-Object[][] example = {
-    {"abc", 123, 1.23},
-    {"xyz", new Object[] { 456L, 7.89f }},
-};
-SecsFormat00 result = sf00FromNested(example);

-<code>
-[[<A 'abc'>, <I4 123>, <F8 1.23000>], [<A 'xyz'>, [<I8 456>, <F4 7.89000>]]]

-Recursively converts a nested ''Object'' array into a SECS structure assuming all leaf elements are strings or nulls. This is often better when you know the expected SecsFormat of your values because the type can be defined explicitly.
