This package is built from the Ghostty source snapshot plus an additional
`orig-vendor-cache` component containing the offline Zig dependency cache used
by upstream packagers.

Why this exists
---------------

Ghostty's upstream packaging guidance expects maintainers to prefetch the Zig
dependency cache and then build without network access by passing `--system`
to `zig build`. Debian package builds cannot download dependencies at build
time, so the prefetched cache is preserved inside the source package as an
extra orig component.

Packaging model
---------------

The source package therefore uses:

 * the Ghostty source snapshot as the main orig tarball
 * a vendored Zig dependency cache as `orig-vendor-cache`

During package build:

 * the prefetched dependency cache is available under `vendor-cache/p`
 * `zig build --system $(CURDIR)/vendor-cache/p` performs the offline build
 * network access is avoided during the package build itself

Current limitations
-------------------

This keeps the package on a Debian-compatible source-build path, but Ghostty
still vendors a large set of upstream dependencies through that offline cache.
Further review work may split or de-vendor those components if Debian sponsors
require it.
