## field_group (`poetry_field_group`)

Class: Poetry::Ui::FieldGroup::Component - BEM block `poetry-ui-field_group`.
- `variant:` (symbol) - one of default|choices, default "default", required - :choices packs a run of horizontal checkbox/switch fields tighter.
- PART `field-group` - The stacking container - fields, fieldsets, and separators render as direct children; also the @container responsive fields measure against
- RULE: Stack Fields (and Fieldsets) with poetry_field_group - the theme owns the rhythm; never hand-space a form column with gap utilities.
- RULE: variant: :choices packs a run of horizontal checkbox/switch fields tighter (the choice-group form).
- RULE: Field's orientation: :responsive is container-driven: it needs a FieldGroup ancestor to measure against - without one it stays stacked.
