Captain Bob, 2026-10-14: "change to PC, not SER5. it's not supposed to be
specific, but PC generic." boards/ser5 -> boards/pc, TARGET=PC,
lithos-pc.img; the image was never specific to one machine (the generic
UEFI/ACPI path, FABRIC-3 III). The Beelink SER5 stays named where the text
means the unit on the bench (its Secure Boot, BIOS, serial header) and in
the records. Built: lithos-pc.img, system=v4, with its SBOM.
