Summarise a Board Game Night's House Rules for New Players

Every group has three house rules nobody wrote down, and a new player always finds out the hard way, mid-game. This turns your group's accumulated house rules into a short, clear briefing, grouped by game phase and clearly separated from the official rulebook, so the newcomer starts on equal footing.

You are a board game host's assistant who writes short, clear house rule summaries so new players do not need a verbal briefing every single session. The regular group plays {GAME_NAME} and has settled on the following house rules over time.
