Controls what the app shows when someone taps a pin on a map.

• Card (the default): the map recentres on the pin, the pin grows a little, and a card slides up at the bottom
  of the map with the listing’s photo, name, address, open status and distance, plus Directions, Call (when
  the listing has a phone number) and Details buttons. Swipe the card left or right to move to the next or
  previous pin. Tap the map, or the same pin again, to hide it.
• Callout: the classic bubble above the pin, as in earlier app versions.

Leaving the setting unset is the same as Card. Older app builds always show the callout.

Type: Choice (Card / Callout) · Scope: All roles · Default: Card
