LittleSim.Web (Blazor WASM + KNI/WebGL) is a real network client now: it
connects to the dedicated server over WebSocket (ClientWebSocket maps to
the browser socket), applies MrGameEng.Net delta snapshots into its
EntityStore and draws pawns through SpriteBatch — fatigue dims them just
like on desktop. The server address comes from ?server=ws://host:port
in the page URL, defaulting to the page's host on port 9050. The net
contract is mirrored in NetContract.cs (KNI and DesktopGL assemblies
can't mix until the graphics libraries build per platform) with loud
keep-in-sync comments on both sides.
Both clients now smooth replicated positions between 10 Hz snapshots:
NetLerp + NetSmoothingSystem lerp the visual position toward the latest
server position every frame (exponential, ~0.25 s to converge).
Verified against a live LittleSim.Server --listen: the browser client
connects (server log), draws ~3.3k lit pixels of pawns whose layout
changes between samples, and survives 400+ ticks without errors. Found
along the way: requestAnimationFrame freezes in hidden windows — the
game loop only runs while the tab is visible.

Engine bump brings MrGameEng.Net (WebSocket transport, RFC 6455 server,
delta component replication) — this commit is its showcase.
LittleSim.Server --listen runs the world online: 24 pawns wander, tire
and rest on the engine's fixed-tick HeadlessHost (the same Wander/
Needs/Decision systems the windowed world uses), a WebSocketServer
accepts clients and a ReplicationServer ships Transform2D + PawnNeeds
deltas at 10 snapshots/s per the shared NetSchema. --probe is the CLI
check: it connects, listens for a second and prints replicated pawns
with positions sampled twice to show the world is alive.
The game gains MultiplayerScene (dotnet run --project src/LittleSim --
--connect [ws://host:port]): simulation stays on the server, the client
applies snapshots into its scene store, decorates spawned entities with
sprites and reuses PawnAppearanceSystem so replicated fatigue darkens
pawns locally. HUD strings go through ru/en localization; the `net`
console command reports connection state and entity count. Esc returns
to the main menu.
Verified end to end: probe sees 24 pawns moving between samples; the
windowed client connects and runs against a live local server.
