## Patches

## Apply the base `patches/` series (top-level *.patch only; *.md/dirs skipped).
## The stock llama-cpp backend is patch-free by default, so this normally does
## nothing. The Makefile `llama.cpp` target already `git apply`s any base patch
## at checkout, so each apply here is `-N` (skip already-applied): re-applying a
## git-format patch with `patch` would fuzzily duplicate hunks. This block only
## does real work if prepare.sh is run against an unpatched checkout.
