Mount Athos icons are not pictures but windows: long-faced ascetic saints raised stroke by stroke from a dark proplasmos base, standing frontal against a burnished gold-leaf ground that reads as divine light rather than empty space. The palette is somber and sacred — madder red, ultramarine, warm clay — closed by a final white illumination on the brow. This system translates that monastic discipline into an interface: flat hieratic gold, hand-built tonal steps, and Greek inscriptions that name rather than decorate. Nothing here is naturalistic; depth is spiritual, not perspectival.
