This is the macOS build for Apple Silicon.

Optional packages
-----------------
  rampart --install --list      see what is available for this build
  rampart --install all         install everything

Local LLM / vector search / embeddings (rampart-langtools)
----------------------------------------------------------
`rampart --install all` installs it -- llamacpp, faiss, clip and
rampart-onnx.  There is one build; nothing else to choose.

llamacpp uses Metal for GPU acceleration.  It is built in -- there are
no drivers or extra libraries to install.

rampart-onnx runs on the CPU by default.  CoreML is available but
opt-in, per session:

  initEmbed(dir, {gpu: true})            or  {provider: 'coreml'}

rampart-graphicsmagick
----------------------
The image module links against a system GraphicsMagick, which is not
bundled:

  brew install graphicsmagick

(If Homebrew is not installed, see https://brew.sh.)  require('rampart-gm')
prints this command for you if the library is missing.
