-====== What Is This Application? ======
-The BinaryLane/Mammoth VPS platform is the software stack that sells, provisions, manages, monitors, and bills VPS services. It combines a large .NET web application with compute-host daemons, network/firewall tooling, backup tooling, and internal operations systems.
-===== What It Does =====
-  * Customer panel actions: create, start, stop, reinstall, migrate, snapshot, resize, and manage networking/firewall settings for VPS instances.
-  * Compute host management: HostDaemon and related scripts execute guest lifecycle commands on physical hosts.
-  * Networking: QEMU/KVM networking, iptables, network namespaces, BIRD routing, NDP/ARP proxying, and router configuration.
-  * Billing and account flows: payment processing, invoices, account management, and API token handling.
-  * Provisioning and images: VM image building, host bootstrap, ISO generation, guest agents, and base-image testing.
-  * Operations: Ansible, monitoring, release tooling, internal bots, CI/CD, and support tooling.
