 - `NEXT_PUBLIC_DEFAULT_THEME = light | dark` sets preferred initial theme (defaults to `system` when not configured)
+- `NEXT_PUBLIC_ZOOM_CONTROLS = 1` enables fullscreen photo zoom controls
 - `NEXT_PUBLIC_MATTE_PHOTOS = 1` constrains the size of each photo, and enables a surrounding border (potentially useful for photos with tall aspect ratios)

 - `NEXT_PUBLIC_ALLOW_PUBLIC_DOWNLOADS = 1` enables public photo downloads for all visitors (⚠️ may result in increased bandwidth usage)
