Some checks failed
C++ Tests / test-fast (pull_request) Successful in 2m40s
API Docs / doc-build (pull_request) Successful in 1m2s
C++ Tests / test-cgal (pull_request) Failing after 11m52s
docs(doxygen): 100% public-API coverage (228 → 0 undocumented)
Completes the work begun in the previous commit on this branch.  Every
public symbol under code/include/ now carries a brief Doxygen comment
(0 undocumented per scripts/doxygen-coverage.sh, with the `detail::`
implementation namespaces excluded as before).

Trajectory on this branch:
  start (after Doxyfile fix):  24.0 %  (165 / 437 in the no-detail set
                                       was 105 / 437 when detail counted)
  after PR #17 base commit  :  42.4 %  (165 / 396)
  this commit               : 100.0 %  (396 / 396)

Files touched (all .hpp / .h headers under code/include/):
  * cgal/Conformal_map_traits.h
  * clausen.hpp, conformal_mesh.hpp, constants.hpp (already docd)
  * cp_euclidean_functional.hpp, cut_graph.hpp, discrete_elliptic_utility.hpp
  * euclidean_functional.hpp, euclidean_geometry.hpp, euclidean_hessian.hpp
  * fundamental_domain.hpp, gauss_bonnet.hpp
  * hyper_ideal_{functional,geometry,hessian,utility,visualization_utility}.hpp
  * inversive_distance_functional.hpp, layout.hpp
  * matrix_utility.hpp, mesh_builder.hpp, mesh_io.hpp
  * newton_solver.hpp, p2_utility.hpp, period_matrix.hpp, projective_math.hpp
  * serialization.hpp, spherical_functional.hpp, spherical_geometry.hpp
  * spherical_hessian.hpp, viewer_utils.h

CI:
.gitea/workflows/doxygen-pages.yml now enforces
`scripts/doxygen-coverage.sh --threshold 100`, so any future regression
(a new public function landed without a `///` brief) fails the build
before the Doxygen HTML is published to Codeberg Pages.

Doxygen warnings remain at 0.

//
// Phase 4b — CGAL::IO wrappers for ConformalMesh.
//
// Reads and writes ConformalMesh (CGAL::Surface_mesh) in standard polygon-mesh
// formats using the CGAL Polygon Mesh I/O utilities (CGAL 5.4+).
//
// Supported formats (detected by file extension):
// .off — Object File Format (read + write)
// .obj — Wavefront OBJ (read + write)
// .ply — Polygon File Format (read + write)
//
// Usage:
// ConformalMesh mesh;
// if (!read_mesh("input.off", mesh)) throw std::runtime_error("read failed");
// // ... process mesh ...
// write_mesh("output.off", mesh);
//
// Note: property maps (lambda0, v_idx, etc.) are NOT serialised — they must
// be re-initialised with setup_*_maps() + compute_lambda0_from_mesh() after
// reading a file.
