Use Photon Realtime’s lobby‑visible custom properties to perform skill‑based matchmaking without a separate lobby. Set <code>CustomRoomPropertiesForLobby</code> on room creation and filter with <code>ExpectedCustomRoomProperties</code> in <code>OpJoinRandomRoom</code>.
Use CSS custom properties for dynamic theming, inheritance, and fallbacks without a preprocessor build step.
Find out how to use Photon Realtime’s custom room properties for dynamic matchmaking—set criteria on room creation, query with JoinRandomRoom, and keep everything inside Photon’s fast server. Includes a Unity example, trade‑offs, and next steps.

Constraint and uncertainty My understanding is that
