+### `location`
+
+`location` is descriptive prompt context included in briefing metadata and
+Scriptorium data packages. It does not select a Weather API endpoint or enable
+multiple configured forecast locations.

+- `id`: short local identifier. Default: `home`.
+- `name`: human-readable location name. Default: `Brentwood`.
+- `region`: broader forecast area context. Default: `St. Louis Metro`.

+The prompt-facing location object also includes `timezone`, derived from the
+effective `weather_api.timezone` after CLI overrides such as `--tz`.

 ### `missing_source`
 
 - `default`: missing-source behavior for optional sources. One of `error`, `warn`, or `none`. Default: `warn`.
