Zij bewijst dat een Card\nof World werkelijk in het ongewijzigde, ondertekende Almanac-manifest staat.\n\nDe controle draait volledig in de browser van de bezoeker:\n\n1. Het ondertekende manifest (`manifest.json`), de handtekening (`manifest.sig`) en\n   de publieke sleutel (`almanac.pub`) worden opgehaald.\n2. De **Ed25519-handtekening** wordt gecontroleerd over exact de manifest-bytes.\n3. De ingetypte 64-teken-**DNA-code** wordt exact opgezocht — van Cards, geneste\n   fysieke kaartjes én Worlds.\n\n\"Authentic\" verschijnt uitsluitend wanneer de handtekening geldig is én de code\nexact voorkomt. Geen server, geen tracking — de kaart overleeft deze website."
