// The launch: what the first install holds, and a launcher for its first two weeks (Jae, 2026-11-01: "Yes, 14-day
// window"). The launcher may add and remove sites, each counting at once, so the exact addresses video sites need
// can be found in minutes rather than a vote each; the guardian and GovDAO can remove anything it adds; it can't
// touch customers, hubs, payers or releases; and its power ends LaunchDays after the first install, for good.
//
// owner, launchSeed and launcher are written by deploy/realm/prepare.py just before the realm is deployed, from the
// hub's real pin and payer and the first release's hashes. The realm is deployed from a hot key (Jae's Ledger can't
// sign a transaction carrying the whole source) under that key's namespace, so the code itself names the owner,
// Jae's cold key: it is the first guardian and holds the first SUGAR; the deploying key ends up holding nothing.
