# Nothing is spawned at run time: FFmpeg is linked, whisper.cpp and
# sherpa-onnx are compiled in. alsa-lib is cpal's playback backend;
# fontconfig and freetype are the font side of the renderer; libglvnd and
# vulkan-icd-loader are the two backends wgpu picks between, and the rest is
# what winit opens by name for whichever session the user is in. dbus is the
# XDG portal, which is how the file dialogs and "reveal in file manager"
# work without a toolkit.

# !debug: the app profile strips symbols itself, so there is nothing left to
# split into a debug package.
# !lto: makepkg's lto puts -flto=auto into CFLAGS, and ring - the crypto
# behind the model downloads' TLS - compiles hand-written assembly through
# cc, which comes out as bitcode and links to nothing. Rust's own LTO is set
# in the app profile and is unaffected.

  # ggml (whisper.cpp's kernels) tunes itself to the machine it is compiled
  # on unless told otherwise. A package is not always built on the machine it

  # --features wgpu: FemtoVG over wgpu instead of the default Skia renderer.
  # skia-bindings downloads prebuilt binaries from its build script, which a
  # package cannot do; the wgpu renderer is pure Rust. This is the same
  # choice, for the same reason, that upstream's flake.nix makes.
  #
  # --profile app: upstream's shipping profile - fat LTO, panic=abort,
  # stripped. See engine/Cargo.toml for what each knob is for.
  #
  # sherpa-onnx-sys, the text-to-speech backend, ships no C++ build: its build
  # script downloads a prebuilt static-lib archive from its own release page.
  # concat pins that archive as a checksummed source; here the version moves
  # with main, so the build script fetches it - build() needs the network.
