Cutting across all of these:

hardware needed to run danos: minimum specs (UEFI x86-64, ACPI, PCIe ECAM,
xHCI, ~128 MiB RAM) grounded in what the boot path actually assumes, plus a
plain-language guide matching Intel/AMD CPU generations by name.
- **[arch.md](arch.md) — the architecture split.** How CPU-specific code is kept
behind a build-time `arch` module so the generic kernel never names x86_64,
leaving room for other systems (e.g. an AArch64 Raspberry Pi) later.
