#   tzdata          — IANA timezone data for TZ environment variable
#   libicu76        — .NET globalization (Debian Trixie specific)
#   libasound2t64   — ALSA audio, required by libraatmanager.so
#   libfreetype6    — provides libfreetype.so.6 soname that bundled libharfbuzz links against
#   cifs-utils      — SMB/CIFS network share mounting
#   ca-certificates — HTTPS for streaming services and cloud APIs
