A pure-fragment total eclipse driven by two-circle overlap geometry: the Moon's dark disc — a hair larger than the Sun — sweeps across the photosphere on an autonomous loop, taking the day from a bright crescent through the deep hush of totality and back out. As the centres close the sky drains to twilight and a hashed star field surfaces; at second and third contact the last bead of photosphere flares into a brief soft diamond ring. Through totality a noise-streamered pearly CORONA fans out past the limb, a thin red chromosphere rings the Moon, and a few pink PROMINENCES arc off the edge. Move the pointer to nudge the Moon's path, scroll to zoom the field, press to force the diamond-ring flash. Everything is additive HDR run through an ACES tone-map and capped below white — no strobe, no clip.
