+Slack publishes Linux builds for x86_64 only. On x86_64 this package installs that `.deb` unchanged, replacing the AUR `slack-desktop` recipe with one Omarchy controls. On AArch64 it runs the same application code on the AArch64 build of the Electron release Slack ships with, so `slack-desktop` resolves to a working package on ARM Omarchy installs too. Everything below applies to the AArch64 build only.
