Subject: [PATCH] Commit baked atlases for all 8 blob-styles; remove atlases/
 from .gitignore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Aligns with the other lib-asset prototype packages (fa-starter,
subterrain) where baked atlases ship with the lib instead of being
regenerated per-consumer. Removes a runtime atlas-baker dependency
for downstream consumers (vagrant-skeleton, map-editor) — they can
load the JSON+PNG pair directly after a plain install-reference
stage without invoking Python+Node toolchains.

Variants committed: blob_concave, blob_diagonal_cut, blob_organic,
blob_rectilinear, blob_rect_grass, blob_rect_stone, blob_rect_wood,
blob_testbench. Re-bake via scripts/bake.sh when sources change.
