Auto-generated API doc: doxygen → custom Python emitter → doc/api/.

`cmake --build build --target doc` runs Doxygen to produce XML, then
`doc/gen_api_md.py` (~330 lines, stdlib-only) emits a Markdown tree
under `doc/api/` that gitea renders directly in its file browser.

- 24 class/struct pages + 51 source-file pages + indices, with source
  links of the form `../../../../src/...#L42` that gitea turns into
  clickable line-anchored links.
- Doxyfile.in templated by CMake (XML-only output to build/doc/xml/).
- Pure Python emitter, zero external deps — no doxybook2 (not packaged
  on Arch) and no moxygen (avoids Node).
- Target gracefully disabled if Doxygen or Python 3 is missing at
  configure time; regular build target unaffected.

+## Protected Functions
+
+### `void add(MapType el_content)`
+
+📍 [syselmts.hpp:47](../../../../src/system/syselmts.hpp#L47)
+
+Adds elements from a map to the container.
+
+**Parameters**
+
+- `el_content` — Map of elements to add.
+
+## Public Functions
+
+### `SystemElementContainer(string name)`
+
+📍 [syselmts.hpp:60](../../../../src/system/syselmts.hpp#L60)
+
+Constructor for an empty container.
+
+**Parameters**
+
+- `` — Name of the container.
+
+### `SystemElementContainer(string name, vector< T * > elements)`
+
+📍 [syselmts.hpp:67](../../../../src/system/syselmts.hpp#L67)
+
+Constructor with initial elements.
+
+**Parameters**
+

+- `elements` — Vector of elements to add.
+
+### `void add(string name, T *element)`
+
+📍 [syselmts.hpp:78](../../../../src/system/syselmts.hpp#L78)
+
+Adds a single element to the container with a given name.
+
+**Parameters**
+
+- `` — Name of the element to add.
+- `element` — Pointer to the element to add.
+
+**Throws**
+
+- `runtime_error` — If the element's name is empty or already exists.
+
+### `void add(T *element)`
+
+📍 [syselmts.hpp:96](../../../../src/system/syselmts.hpp#L96)
+
+Adds a single element to the container.
+
+**Parameters**
+
+- `element` — Pointer to the element to add.
+
+**Throws**
+
+- `runtime_error` — If the element's name is empty or already exists.
+
+### `bool exists(string name)`
+
+📍 [syselmts.hpp:106](../../../../src/system/syselmts.hpp#L106)
+
+Checks if an element exists in the container.
+
+**Parameters**
+
+- `` — Name of the element to check.
+
+**Returns** True if the element exists, false otherwise.
+
+### `void add(SystemElementContainer< T > *elements)`
+
+📍 [syselmts.hpp:123](../../../../src/system/syselmts.hpp#L123)
+
+Adds elements from another container.
+
+**Parameters**
+
+- `elements` — Pointer to another container.
+
+### `void add(vector< T * > elements)`
+
+📍 [syselmts.hpp:132](../../../../src/system/syselmts.hpp#L132)
+
+Adds multiple elements from a vector.
+
+**Parameters**

+
+### `T * get(string name)`
+
+📍 [syselmts.hpp:146](../../../../src/system/syselmts.hpp#L146)
+
+Retrieves an element by its name.
+
+**Parameters**
+
+- `` — Name of the element to retrieve.
+
+**Returns** Pointer to the element.
+
+**Throws**
+
+- `runtime_error` — If the element is not found.
+
+### `T * merge(string name)`
+
+📍 [syselmts.hpp:164](../../../../src/system/syselmts.hpp#L164)
+
+Merges an element by retrieving it or creating a new one if it doesn't exist.
+
+**Parameters**
+
+- `` — Name of the element.
+
+**Returns** Pointer to the merged or newly created element.
+
+### `size_t size() const`
