Steampunk Sun Crown Priestess

Create a vertical dark fantasy steampunk portrait of an ethereal priestess or clockwork sun queen wearing an enormous heavy golden solar crown. The figure is centered, shown from upper body to knees, with a deliberately featureless face obscured by a smooth muted beige square panel, long flowing {argument name="hair color" default="silver-white"} hair whipping outward in many fine strands, and a voluminous white ceremonial robe with layered drapery and black shadowed undersides. The crown is the dominant subject: a huge circular polished brass disk over the forehead like a mechanical sun, surrounded by ornate filigree rings, tiny gears, radial latticework, and exactly 16 prominent sun rays: 8 large broad triangular spear rays and 8 thinner needle-like rays alternating around the halo. Add small dangling star ornaments beside the head. Across the chest, place a dark mechanical collar or breastplate with exactly 4 visible round clockwork medallions: one large central clock-like disk, two medium side dials, and one smaller compass-like disk; from it hang multiple bead chains with exactly 5 visible pendants: a small pointed cone, a small star, a large star-gear, a large pentagram ring, and a small round orb. Set the scene inside a vast dim {argument name="setting" default="gothic cathedral clock tower"} with tall arched windows, bronze pipes, ornate clock mechanisms, and exactly 4 background timepieces visible: a large clock in the upper left, a large clock in the upper right, a smaller hanging clock on the right, and an astrolabe-like circular instrument on the left. Use cinematic chiaroscuro lighting, warm brass highlights, cool gray shadows, shallow depth of field, ultra-detailed metal engraving, realistic fabric folds, symmetrical sacred composition, and a majestic yet slightly eerie mood. No text, no watermark, no modern objects.
