A depot at Sun–Earth L2 where sunshield membranes get swapped, instrument modules pulled and reseated, and tanks refilled by a five-metre arm. The ground is the artefact: five layers of Kapton E, aluminized on both sides, folded flat under cleanroom lights.

Everything reads as a working document. Wide margins, squared frames, leader lines running to numbered parts, torque values set in mono. The purple-pink cast on the outer layers is a doped-silicon coating artefact, not a palette choice — and the gold is 100 nm on eighteen mirror segments, nowhere else.
