A Chair in the Photoevaporating Cathedral of Carina I positioned the observer 6 light-years from a pillar tip inside NGC 3372, meters from a half-buried basalt boulder bearing a weathered wooden chair, to witness 10,000 K Hα sheaths peel from a 30–300 K molecular column while a 40,000 K, 10^5 L☉ newborn star backlights the scene. Here we see UV-etched rims glowing copper-amber (JWST-like NIR), OIII filigree in teal, and radial shafts carving the dust like stained glass; the protoplanetary disk faintly warms at 150–800 K. This frame captures an impossible intimacy—telescope-grade detail from within the nebula—where the ordinary seat faces parsec-scale architecture dissolving under young starlight, the scale palpable in diffraction spikes and kilometer-per-second photoevaporation flows.
