# Platform Abstraction Layer. The headers are included as <pal/...> (matching
# the CMake build's `include_directories(runtime/pal/include)`). They are
# exposed through a header map (dict `exported_headers` with an empty
# namespace) instead of an `-I` flag, so the short <pal/...> include resolves
# identically under both the fbcode (`cpp_library`) and xplat
# (`fb_xplat_cxx_library`) rules, which do not share an include-dir attribute.
# Kept in their own library so the mapping does not disturb the runtime
# target's namespaced <executorch/...> exported headers.
