 * Charge par index.html SEUL : sa version vit a un seul endroit.
 * Deux schemas, et chacun dit ce que le texte d'a cote dit deja :
 *  1. le trajet d'une demande, sous « Ou s'arrete la demande ? » : trois
 *     passages s'arretent chacun a un des trois points de la liste, le
 *     quatrieme va jusqu'au devis. AUCUN pourcentage : on montre ou une
 *     demande se perd, on n'invente pas combien ;
 *  2. le devis qui se coche, dans « Un projet defini avant de commencer » :
 *     ses cinq lignes sont celles du paragraphe voisin.
 *
 * Sans mouvement demande (ou sans animation possible), les deux schemas
 * sont IMMOBILES ET COMPLETS : les trois arrets numerotes, et le devis coche.
