The map draws markets, workplaces coloured by trade, carts, merchants,
crop fields that turn gold when ripe, every home and dashed shard
borders. The side panel lists each person's job and coins and shows
economy and employment statistics. The server includes `crop_ripe` in
the state.

The server is now a gateway that starts SIM_SHARDS shard processes
(`sim shard --index I --count N ...`), each with its own database from
the SHARD_DATABASE_URL template. The gateway steps all shards in
lockstep over a /control WebSocket, publishes the entity directory and
market board between steps, merges the shards' views into one world
for the UI and routes edits to the shards they concern.
Shards send entity messages and transfers to each other directly over
/remote WebSockets; every step waits until its outgoing messages are
accepted, so nothing is in flight when the next step starts or a
snapshot is taken. Shard processes exit when the gateway goes away.
Update Picard to f88b9cb and register every other shard as a console
peer `shard-N`, so one console session can list, inspect, manage and
message the actors of all shards.

Each shard founds markets and workplaces (farms, woodcutters, quarries,
hunters, toolmakers, cartwrights). Adults are hired, commute to work,
sell their goods at the market, get paid and go home. Markets, workplaces
and carts are actors; prices follow local supply and demand and trades
are haggled. Merchants trade with markets on other shards through the
router, so they do not know whether a market is remote.

Add a router that delivers actor messages locally or to the shard that
currently hosts the entity. People and animals that leave their shard's
columns depart with their full state, forward messages while in flight
and are re-admitted on the destination shard. Enlarge the default world.

Add tracing, tungstenite and uuid as workspace dependencies for the

People, rabbits, wolves and partnerships are now Picard actors that own
their state and apply their own rules (ageing, hunger and meals,
starvation, energy, breeding costs, death, birth intervals). The world
no longer keeps mirrored Vecs that were read from and written back to
generic entity actors every step; it only reaches entities through
typed messages and replies, correlated by request id through a single
inbox actor.
World-level state (terrain, resources, stockpile, houses, calendar, the
world random stream) stays in the world, and behaviour decisions stay
on the simulation thread because the Rune VM is not Send. Replies are
processed in entity order and each person has its own persisted random
stream, so runs and snapshot restores stay deterministic.
Rabbits killed by hunters no longer move or breed later in the same
tick.
BREAKING CHANGE: Picard actors are named person-<id>, rabbit-<id>,
wolf-<id> and partnership-<id> instead of entity-<id>, which changes
the paths used with the actor console.

The defaults in config.rn changed (90 initial people, fertile teens and
older adults), but the tests still hard-coded the previous 9-person
village. Tests now override Rune constants by name and compute expected
counts from the loaded configuration.

- Replace signed coordinate round-trips with checked offset helpers
- Use From/try_from conversions and clamp helpers in the edit parser
- Isolate exact RNG, noise and day-fraction float casts in documented helpers
- Split long functions (validate, world creation, apply, state_json, tick_person)
- Pass run_sim shared state by reference and tidy remaining style lints
Simulation behaviour and RNG sequences are unchanged.

Replace lossy casts with checked tile/canvas helpers, use map_or_else and

Collapse nested ifs, use is_multiple_of, pass the editor apply callback
directly, and make dropping the actor system shutdown future explicit so
`cargo clippy --workspace --all-targets -- -D warnings` passes.

Starting values and tuning constants are now `pub const` items in a
single Rune file, config.rn, alongside the `person`, `rabbit` and `wolf`
behaviour functions. The behaviours read the constants directly. At
startup the server loads the file from SIM_CONFIG (default: config.rn),
reads and checks every constant, and test-runs each behaviour, so a bad
or missing value stops startup with an error that names it.
- Map width and height can now be configured and are stored in
snapshots.
- The UI's edit limits (max speed, stock, inventory, hunger, energy,
resource amounts) come from the config.
- The in-browser script editor now edits config.rn. Applied edits update
behaviours and tuning values immediately; map size, initial population
and calendar defaults apply on reset.
- The Docker image includes config.rn, and Compose mounts the
repository's copy read-only.
- Documents the config file and how it works in the README.
BREAKING CHANGE: src/behavior.rn has been removed; behaviours now live
in config.rn. The server will not start without a valid config file.
Snapshots no longer store the behaviour script: on restart, config.rn
from disk replaces any edits made in the browser editor.

Use terrain-aware pathfinding for travel toward home and resources so settlers do not get stranded against blocked terrain. Add a startup food reserve, slow hunger accumulation, let villagers return for food sooner, ensure available food is consumed before starvation, and make the first birth check available at the first weekly boundary.

Poll the state endpoint while the WebSocket is not open so browsers that fail to establish the socket still receive initial state and continue updating the UI. Retain WebSocket streaming as the primary transport.
