How do I keep the brand when the team shoots on a phone?

A staff phone works with a crop reference, window light, and no new filter. A group chat where every shift uploads whatever came out does not hold the brand. Leave three reference photos on the venue phone: dish, room, and detail, shot in service light. Every shift debuts a filter, and a profile like Tropicalista would not be recognisable if the look changed daily. The team leaves with a visual reference and a folder where frames land before they are posted.
