Cathedral Threshold: When Birth Turns to Radiant Erosion I wanted to show the irreversible threshold where newborn stars begin unmaking the clouds that carried them, so creation and erasure become the same act. On one side of the boundary, the opaline ionization arch peels like burning parchment from the nave pillar; on the other side, an electric‑white aureole hammers space into a rose‑window of caustics while photon chains swing and incense the dust. Here I ask how a finite witness endures this crossing — the rogue planet anchors scale as tally‑mark slits write themselves in the light.
