The Deck Standard
The one shape every lesson of the deck is held to, so that a dozen pages made by different hands read as one hand.
The standard says who is reading: a thoughtful, busy person who has just said yes to an invitation and gives a page ninety seconds, and the agent that person may hand the page to, which will read every word literally. Every page must serve both, and must be safe when an agent reads it. From that follow the parts, in one order — the top card, why it matters, the way, know it by heart, where players stumble, for your agent, with gratitude — so that whoever can read one lesson can read them all.
It is load-bearing because it is what makes a deck a deck rather than a pile. It fixes the voice (second person, plain words, warm and exact, never grand), it forbids makers' talk on a public page, and it forbids naming any person: a lesson speaks as the Game, uses invented figures in its examples, and never tells the story of how it came to be. Anything a maker has not settled goes into the keepers' notes beside the page, never onto the page, and the page carries only what is settled and true today.
A Player+ meets the standard mostly through its effects: one plain line for every key word at first use, a practice doable from the top card alone, an observable sign that it worked, and a closing section that can never be mistaken for an order from a stranger. A maker meets it directly, and delivers two files — the public page and its keepers' notes.
It also holds one Lexicon for one LIØNSBERG: a word means one thing across the canon, the Game and the deck, and a word used two ways is a defect to repair in one of them.
