Craft a Camera (iron + glass pane + redstone)
Use it, and click: the HUD and your hand vanish for a split second, a flash fires and your view becomes a Photograph, signed "📷 by Zkev1, Day 12" in the lore.
Photos are real locked map items so hang them in item frames as wall pictures using pure vanilla rendering and syncing.
Paper cost, cooldown, and flash are configurable in game.
