Evidence

The native debug viewer consumes about 200% CPU on an Apple M3 Pro while rendering the 50x50 world.
The Ward shell-run verb launches a fully unoptimized Bevy build.
SimHost changes every frame for cadence accumulation, causing snapshot projection and hundreds of text updates to rerun between simulation ticks.

Acceptance

The normal native viewer command uses an optimized interactive profile.
Snapshot-driven projection runs only when the authoritative snapshot changes.
Frame animations and controls remain responsive.
Native CPU/frame pacing improves materially on the same 50x50 world.
Ward tests and the Wasm image build pass.
