// Gaming: what the machine is doing now, and what it should do while you play.
//
// Live first, because unlike every other page here this one has a genuinely
// live dimension -- "is Game Mode actually on, and how hot is the card" is the
// question that brings someone here mid-session.
//
// The part that makes this Panama's page rather than a gamemode config editor
// is "While a game is running": gamemode runs a script when a game starts and
// another when it exits, so the power profile and Do Not Disturb can follow the
// game and be put back afterwards -- back to what they were, not to a default.
