   ÉLÉVATION DU 19/09/2026 — « Les racines » : le réseau du relief pousse en or.
   Le tableau est rendu par le moteur commun (terrae-matiere.js) : le même terrain que « La terre », réellement éclairé.
   La page lui laisse la place : les lumières peintes en CSS ne doublent plus celle du moteur ; le grand monogramme
   est réservé à la finale du récit ; la phrase, que le récit coupait avant son apparition, arrive à temps,
   dans la fonte réellement chargée par Terrae, posée à gauche dans la réserve calme du cadre.
