# Room logic. "sync" keeps the engine Send+Sync (the HTTP surface shares
# GameState across threads); "no_time" bans wall-clock from scripts, so a
# replayed script is bit-identical — the whole CPU-speed-bug class, deleted.
#
# default-features = false drops exactly one thing from rhai's default set:
# `ahash/runtime-rng`, which seeds hash maps from the OS entropy pool. We
# want the compile-time seed instead — one less source of run-to-run
# variation under a crate whose whole promise is byte-identical replays —
# and it's also what makes wasm32-unknown-unknown build at all (runtime-rng
# pulls getrandom, which has no default backend there). "std" is the rest of
# rhai's default and stays on.

# Native-only: the HTTP surface and the AI parser lane don't exist in
