Main independently adopted the engine Core/Host split in G1, so the
scene adaptations conflicted with identical changes here — resolved in
main's favor (its scenes also carry the gene-driven world). Kept from
this branch: BootScene's --connect path into MultiplayerScene, the
buildAtlases switch in GameContent.Load (with the Task.Run lambda fix
its optional parameter requires), net.* localization keys, and the
Net/Server/Web projects in the solution. Program.cs now has both CLI
modes: --check-content (main) and --connect (here). The engine pointer
lands on d044caf, which linearly contains both lines of work.
Verified on the merged tree: 366 engine tests pass, --check-content
reports genes/traits intact, and a live --listen server replicates
moving pawns to the probe.

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.

spikes/KniWeb (outside LittleSim.sln): a kni-blazor-gl template project
(KNI 4.2.9001, net8.0) referencing MrGameEng.Core directly. A mini-host
in the GameHost mold drives EngineContext/GameClock/Scene phases over
KNI's Game; the scene moves 300 Friflo entities in the update phase and
draws them with SpriteBatch (WebGL). Verified in a real browser: sprites
render and animate, browser console is clean.
Decision (docs/web-client.md): path A — KNI — is the primary route for
the web client; the core runs in Blazor WASM unchanged thanks to the
Core/Host split. Known follow-ups: per-platform compilation of the
graphics libraries against nkast.* packages, shader compatibility for
Renderer2D, HTTP-served content instead of the filesystem.

Engine bump: MrGameEng.Core is now platform-free (Friflo only), the
windowed MonoGame host lives in the new MrGameEng.Host library, and the
core gains HeadlessHost — a fixed-timestep loop without a window or GPU.
Game side: scenes switch to Transitions.Fade from the Host library,
WorldScene reads the graphics device via Context.GetGraphicsDevice(),
GameContent.Load(buildAtlases: false) skips atlas building for headless
runs.
LittleSim.Server is the dedicated-server seed and the showcase for
HeadlessHost: it loads mods/defs without textures and fast-forwards the
world calendar and climate on a fixed tick (~3.6M ticks/s in Debug):
dotnet run --project src/LittleSim.Server -- --days 10 --tps 60
