AARCH64 whl cannot resolve ARM64 exe path

[Crozzers]

I installed this lib on a raspberry pi, but when I go to trigger it like so:

from sass_embedded import compile_directory
compile_directory(STYLES_DIR, OUT_DIR, no_sourcemap=True)

I get the following error:

Traceback (most recent call last):
  File "/tmp/website/src/make_styles.py", line 18, in <module>
    compile_directory(STYLES_DIR, OUT_DIR, no_sourcemap=True)

FileNotFoundError: [Errno 2] No such file or directory: '/home/server/.venvs/website/lib/python3.13/site-packages/sass_embedded/dart_sass/_ext/1.93.2-linux-aarch64/dart-sass/src/dart'

Upon investigation, it seems like the aarch64 wheel being distributed through PyPI installs the ARM64 version:

This isn't necessarily a problem, since it seems to still run, at least on my machine:

$ /home/server/.venvs/website/lib/python3.13/site-packages/sass_embedded/dart_sass/_ext/1.93.2-linux-arm64/dart-sass/src/dart --version
Dart SDK version: 3.9.3 (stable) (Tue Sep 9 12:02:51 2025 -0700) on "linux_arm64"

I suspect this issue comes down to how the library resolves the dart exe, and how it decides which arch to use, perhaps here? No mention of aarch64?

sass-embedded-python/src/sass_embedded/dart_sass/__init__.py

Lines 36 to 44 in 1bf8bdb

	def resolve_arch() -> ArchName:
	"""Retrieve cpu architecture string as dart-sass specified."""
	# NOTE: This logic is not all covered.
	arch_name = platform.machine()
	if arch_name in ("x86_64", "AMD64"):
	arch_name = "x64"
	if arch_name.startswith("arm") and arch_name != "arm64":
	arch_name = "arm"
	return arch_name # type: ignore[return-value]

Don't have time right this second, but happy to investigate further and submit a fix later this week
Scratch that, fix seems to be easier than I thought

Oh apparently aarch64 and arm64 are the same thing, there are just different names:

Make sense the compatibility then
