# rand 0.8 pulls getrandom 0.2, which on wasm32-unknown-unknown refuses to
# compile unless its "js" feature is explicitly enabled (it calls into the
# Web Crypto API via wasm-bindgen). Bevy's own rand usage is on getrandom
# 0.3+, which enables this by default; our direct rand 0.8 dep does not.
# Force-enabling it here unblocks the web build. See getrandom docs:

# Desktop release tuning. This renderer is GPU-bound, but Bevy's CPU path
# (resource management, system scheduling, egui, wgpu command submission)
# still benefits measurably from cross-crate LTO and a single codegen unit:
# - lto = "fat": cross-crate inlining, removes trampolines through Bevy/wgpu.
# - codegen-units = 1: best optimization, at the cost of slower compiles.
# - panic = "abort": smaller binary, no unwind tables in the hot path.
# - strip: drop debug symbols from the shipped binary.
# `wasm-release` inherits release, so web picks these up too (then overrides
# opt-level to "z" for binary size).
