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.

Engine pointer -> 10898b0, which brings in two engine changes:
- the gene-system formula engine (Core): a data-driven expression
evaluator that compiles a def string once and evaluates it
allocation-free against a variable context;
- a parallel refactor splitting the platform out of Core into a new
MrGameEng.Host library.
Game migration for the Host split: reference MrGameEng.Host (+ add it
and its test project to the solution), import MrGameEng.Host where
GameHost/GameHostOptions/Input are used, switch Transition.Fade ->
Transitions.Fade, and read the device via context.GetGraphicsDevice()
now that EngineContext is platform-free.
Showcase the formula engine with a dev-console 'formula <expr>' command
that compiles and evaluates an expression. Also adds docs/гены.md, the
gene-system design doc (phases G1-G5).

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

- Added new UI strings for menus, settings, and pause functionality in both English and Russian localization files.
- Introduced a new WorldPresetDef class to define world size and population settings, allowing for dynamic world creation.
- Updated world generation logic to support customizable terrain smoothing and population settings based on user-defined presets.
- Refactored WorldScene to utilize the new WorldConfig structure for improved world initialization and loading.
This commit improves the user experience by providing more options for world creation and enhancing the overall localization of the game.
Wire the engine's new MrGameEng.AI module into a PawnBrain for world pawns,
plus surrounding content/scene tweaks. Apply CSharpier across the game and
document the convention in CLAUDE.md. Add .vscode/settings.json so the editor
formats on save with the CSharpier extension.
The whole game is now described by Mods/Core — the first consumer of
the engine's new MrGameEng.Mods module:
- textures/ moved to Mods/Core/Textures; atlases are built at game
start from the merged texture tree of all active mods into Cache/
(gitignored, incremental) instead of being committed, and the
GameAssets atlas handles are gone with them
- terrain, plants and pawns are JSON defs (Mods/Core/Defs) with parent
inheritance; scenes read TerrainDef/PlantDef/PawnDef instead of
hardcoded arrays, and the TerrainKind enum is retired
- HUD strings come from Mods/Core/Languages (ru default, en fallback)
through LanguageManager; the language switches at runtime
- new console commands: mods, lang [code], defs [type]; atlas now
inspects the runtime-built cache
- bump engine: MrGameEng.Mods module and the explicit-sources
AtlasBuilder overload

MrGameEng.Pathfinding (A*/Dijkstra/BFS + flow fields for crowds) and
MrGameEng.Collisions (spatial hash, pairs/queries/raycast) are now in
LittleSim.sln. Flow fields are the planned steering tool for villagers.

God-game: minimal graphics, deep simulation. The engine lives in the
engine/ git submodule and its sources plus test suites are part of
LittleSim.sln, so engine and game are developed in one editor window.
Playable skeleton: seed-deterministic terrain (smoothed height field ->
water/sand/grass/forest/mountain tinted cells), 80 wandering villagers
on a Y-sorted layer, god camera (WASD pan, wheel zoom, world-bounds
clamp), HUD and the dev console with a 'regen [seed]' command.
CLAUDE.md sets the game rules: simulation-first, one-seed determinism,
simulation/presentation split, a console command for every mechanic.
Design docs in Russian under docs/.
