• cgv_set_edge_colors() — set per-edge RGBA colors (default: average of endpoint colors).

• cgv_layout_fr() — Fruchterman-Reingold layout in 2D/3D (pure R).
• cgv_layout_fr_bh() — Barnes-Hut FR (O(n log n)) in C for large graphs.
• cgv_camera_mode() — switch camera mode (fly / orbit / arcball).
• cgv_fly_path() — animate camera along waypoints (Catmull-Rom spline).
• cgv_record_start() / cgv_record_stop() — video recording via ffmpeg pipe.
• cgv_is_stub_build() — TRUE when the package was installed without Vulkan / GLFW (stub build). Native APIs raise a clear error in that case.

• macOS support: configure auto-detects Darwin, sets OS_MACOS=1, picks Vulkan from VULKAN_SDK/macOS/, VULKAN_SDK/, or Homebrew (/opt/homebrew/lib, /usr/local/lib), and applies -mmacosx-version-min=12.0.
