+"""Climate platform for Local Things.
+
+The first composite entity in this integration: a single HA climate card that
+unifies several OCF resources of a Samsung air conditioner. Unlike every other
+platform here (one descriptor -> one resource field), a climate entity reads
+power, HVAC mode, current/target temperature, fan (wind) strength, swing (wind
+direction) and the convenient-mode preset from *different* resources.
+
+It binds one primary `BoundEntity` (the `/mode/vs/0` capability) so the registry
+still tracks it, and reads the sibling resources straight from the coordinator
+snapshot via `coordinator.resource(href)` -- the same cross-resource read that
+`number.py` (live range/unit) and `select.py` (options callable) already do.
+
+Writes go through `coordinator.async_send_command(bound, (kind, value))`: the
+CLIMATE capability's `write_fn` maps each `(kind, value)` payload to the right
+`(path_segs, body)`, and `async_send_command` POSTs to those path_segs (the
+bound href is only used for logging), so one descriptor drives writes to power,
+mode, temperature and wind resources.

+"""Capabilities for the Samsung air-conditioner family (ARTIK051_PRAC-class).
+
+Resources verified against the issue #17 diagnostics dump (model
+ARTIK051_PRAC_20K). This is the first family whose core controls surface as a
+single composite HA `climate` entity rather than a scatter of switches/selects:
+power (on/off), HVAC mode, current/target temperature, fan (wind) strength,
+swing (wind direction), and the convenient-mode preset all live on one climate
+card. The climate platform (climate.py) reads those sibling resources from the
+coordinator snapshot; here we bind the primary `/mode/vs/0` resource to the
+`ClimateDesc` and mark the consumed siblings as covered.
+
+None of these caps may go into the global `ALL`/`CAPABILITIES`: `/mode/vs/0`,
+`/temperatures/vs/0`, `/humidity/*` collide with fridge/oven hrefs of a
+different schema (see capabilities/__init__.py). They live only in the AC
+by_type registry.
