Pre-history-rewrite snapshot

Frozen snapshot of EBGeometry before the history rewrite that purged large
binary blobs (meshes, generated docs) from main's history.

This repository preserves every pre-rewrite commit SHA, so a downstream project
that pins EBGeometry as a submodule at an old commit can keep building by
pointing the submodule URL here.

Migrating a submodule pin

Quick unblock — keep your existing (old) SHA, just repoint the URL:

git config submodule.<name>.url https://github.com/rmrsk/EBGeometry-legacy.git
git submodule sync && git submodule update --init

Proper migration — move to the rewritten history on the main repo. Look up
your old SHA in the attached EBGeometry-commit-map.txt (format:
<old-sha> <new-sha> per line), set your submodule to the new SHA, and repoint
the URL back to https://github.com/rmrsk/EBGeometry.

Consumers that vendor EBGeometry.hpp onto their include path (not as a
submodule) are unaffected.
