### What did you do (e.g., steps to reproduce)
I followed the installation steps up and including 'bundle exec jekyll serve'.

### What did you expect to happen?
The site to be served.

### What happened instead?
I got the following error and the site did not serve.

/var/lib/gems/3.1.0/gems/sass-embedded-1.69.5-x86_64-linux/lib/sass/embedded/connection.rb:41: warning: /var/lib/gems/3.1.0/gems/sass-embedded-1.69.5-x86_64-linux/ext/sass/dart-sass/src/dart: error while loading shared libraries: /lib/x86_64-linux-gnu/libc.so: invalid ELF header
Conversion error: Jekyll::Converters::Scss encountered an error while converting 'assets/main.scss':
end of file reached
bundler: failed to load command: jekyll (/usr/local/bin/jekyll)

### Additional information

Beginne damit, den gemeldeten Fehler bei `bundle exec jekyll serve` zu reproduzieren, und untersuche die Konvertierung von `assets/main.scss`. Der Fehler verweist auf die `connection.rb` von sass-embedded und auf einen ungültigen ELF-Header in der gebündelten ausführbaren Datei von Dart Sass; als erledigt gilt die Aufgabe, wenn die Website lokal ohne den SCSS-Konvertierungsfehler bereitgestellt wird.
