One file (variables.nix) holding every value that was previously hardcoded and repeated across modules: LAN domain/CIDR, home/tailnet domains, cross-host references (nix-cache substituter hostname, NFS server hostname, remote-builder user), PXE/PBS IPs, timezone, and the primary username. Wired in via flake.nix's specialArgs (and home-manager's extraSpecialArgs for the two home.nix files), so any module picks it up by just adding `vars` to its function arguments — no explicit import needed. Two hosts (nix-cache, server) now derive their own networking.hostName from the same variable other hosts use to reach them, so there's exactly one place to change either identifier. Purely mechanical: every substituted value matches what was already there, confirmed by identical toplevel .drv paths for all 17 targets before and after.
