def coerce(value, attribute:)
  case value
  when true, "true", 1, "1" then true
  when false, "false", 0, "0", nil then false
  else
    raise Riffer::ArgumentError,
      "#{attribute} must be a boolean (or 'true'/'false'/'1'/'0'/1/0), got #{value.inspect}"
  end
end

Coerces value to a boolean so an env-var +“false”+ (truthy in Ruby) doesn’t silently read as true. Raises Riffer::ArgumentError on an unrecognized value, naming attribute in the message.
