    data: { lexxy_key: key }

def lexxy_variables_prompt(context: nil, trigger: "{{", empty_results: "No variables found")
  items = Array(LexxyVariables.config.resolve_catalog(context))
  render partial: "lexxy_variables/prompt",
         locals: { items: items, trigger: trigger, empty_results: empty_results }
end

#render_variable_content(rich_text, context: nil, locale: I18n.locale, assigns: {}, **inline_assigns) ⇒ Object

assigns: (and any extra keyword args) are per-render values merged on top of the configured assigns, so a caller can supply a key's value inline:

render_variable_content(@record.body, first_name: @user.first_name)

Inline values win over the configured assigns. Keys not used by any chip in the body are ignored. Under the default renderer inline values are HTML-escaped; under Liquid they are emitted as-is, so pre-escape them or pass a drop.
