# Layer 13: Real assets over the mesh (textures, models, audio) (HyperOverlay)
#
# Layer 12 moves synthetic noise between two peers. This one moves the game's own
# texture files, checks they still decode as images on arrival, and checks that a
# peer which fetched one can serve it to a third peer after the origin is gone.
#
# Assets are staged from the hyper-tps working tree. They are NOT copied into the
# repo: they are large, they already exist, and a test fixture that duplicates
# 8 MB of PNG into git is its own problem.

# ---- Stage real textures ----
# A JPEG and three PNGs of different sizes: enough chunks to exercise the
# scheduler, small enough that the suite stays runnable.
# A MIXED set on purpose. The overlay is content-addressed and type-blind — it
# chunks bytes and verifies blake2b, and nothing in the path inspects a format —
# but "it should be type-agnostic" is a claim, not a result. A game needs to move
# models and audio as much as textures, so the suite moves real ones of each and
# validates them per format on arrival.
