Arch ships steam for x86_64 only, so on AArch64 `omarchy-pkg-add steam` found nothing. This aarch64 build installs the same Valve launcher files (desktop entry, icons, steam-devices udev rules) but replaces the x86 bootstrap with Valve's native arm64 client, which then updates itself from the stable steam_client_linuxarm64 channel. The bootstrap is just the client binary, which links only glibc, taken from the manifest's bins_linuxarm64_linuxarm64 zip and pinned to the sha2 the manifest publishes. /usr/bin/steam unpacks it on first launch, keeps the ~/.steam links the client requires, and restarts the client when it exits with 42 after updating. Valve's bin_steam.sh cannot do this: it only knows the ubuntu12_32 bootstrap. Beyond Arch's dependencies the client needs gtk2 and libibus for its UI, and lsof, which it runs to find its own IPC ports.
