  These files are embedded into the z13gui binary with //go:embed, so every
  built binary and every release artifact contains the font. The OFL requires
  its notice to travel with the font, which is why LICENSE-Inter.txt is shipped
  in the release archive and installed by the distribution packages rather than
  only living in the source tree.

z13gui links dynamically against GTK 4 (LGPL-2.1-or-later) and
gtk4-layer-shell (MIT), and statically against its Go module dependencies.
Neither the shared libraries nor the Go dependencies' source are redistributed
here; their licenses are recorded in go.mod / go.sum and in the respective
upstream projects. Run `go list -m all` for the current dependency set.

The eBPF program in internal/gui/gamepad/hidblocker/blocker.bpf.c declares
"GPL" in its license section. That declaration is required by the kernel to
call GPL-only BPF helpers (BPF_CORE_READ expands to bpf_probe_read_kernel) and
is what the kernel's module licensing check reads — it is not a statement about
this repository's copyright license. See that file's header for the specifics.
