/* ============================================================================ * deck-gate.css — THE ONE CONDITION that decides whether a page may offer a * board deck, and THE ONE OWNER of whether the control is on screen. * * Shirish, 2026-08-20: "There is no board deck except in KYP right now and * nowhere else." * Shirish, 2026-08-21: "Bankers need to get a working button right away." * Know Your Peers has the deck. A white-label copy of Know Your Peers IS Know * Your Peers, so it has the deck too. The copy was being read as a different * page and refused. That was an identity bug, not a policy. * * HOW A PAGE SAYS IT HAS A DECK * — and nothing else. No path list, no name test. * The declaration is a property OF THE PAGE, so a copy of the page carries it * in the copied bytes. That is why a white-label clone works the day it is * made, under a name this file has never seen. Absent the attribute the deck * is off: DEFAULT DENY. * * WHY CSS AND NOT A SCRIPT FLAG. Row 106/113 lineage: a deck button was once * hidden in markup and un-hidden from script; when the script died at parse time * the flag read `true` while the button rendered 0x0 — the source said one thing * and the page said another. So the attribute is static bytes and the rule is a * stylesheet: no script has to survive for the page to look right, and if the * script does die the deck is off in BOTH halves at once, never one. * * TWO THINGS DECIDE WHETHER THE BUTTON IS SEEN, AND BOTH LIVE HERE: * CAPABILITY --statum-deck, from data-deck above. Does this page have a deck. * STATE .is-ready, set by the page when there is something to put in a * deck. The page owns WHEN, this file owns WHETHER. The page must * never write display on these controls: one control, one owner. * * deck-gate.js reads THIS SAME PROPERTY to decide whether the deck service may * be called, so the look and the money are governed by one declaration. * ========================================================================== */ :root { /* ------------------------------------------------- THE FLAG: default deny */ --statum-deck: none; } :root[data-deck="on"] { --statum-deck: block; } /* Every deck trigger in the estate, by the id the house uses.
