A scale comparison wheel prompt for GPT Image V2

[subject] = (type: "a single sars-cov-2 virion (120 nm diameter)," "a 3 nm gate-all-around transistor channel," "a tardigrade (hypsibius dujardini, 0.5 mm)," "the hubble ultra deep field galaxy z~10 candidate," etc.)

design a hyper-realistic 3d logarithmic scale wheel infographic that positions [subject] precisely within the grand hierarchy of length scales from planck length to the observable universe.

layout structure (critical):
- the layout is a polar coordinate system. at the exact centre, a magnificent, hyper-detailed 3d model of [subject] is displayed on a circular podium of black glass. a ring of light on the podium edge highlights the subject's scale.
- radiating outward are concentric, logarithmically-spaced rings. the radial coordinate r corresponds to log₁₀(length in metres). the rings are calibrated with fine tick marks and labelled in si prefixes: fm, pm, nm, µm, mm, m, km, mm, gm, au, ly, pc, gpc.
- objects are placed along their respective rings at angular positions that distribute them evenly, with the size of each object's 3d icon in the scene exactly proportional to its real-world size relative to a constant display scale (so a 1 µm bacterium appears 1000× the diameter of a 1 nm protein).
- some objects overlap size ranges? a callout bracket spans multiple rings for objects with a size range.
- a master logarithmic scale arc ruler runs along the outermost perimeter.

detailing per object:
- every object on the rings (there should be 50–70 objects) is a tiny but exquisitely detailed 3d model. beside each model is a data flag:
  1. object common and scientific name
  2. characteristic diameter in metres (scientific notation, e.g., "2.5 × 10⁻¹⁰ m")
  3. a relatable size analogy (e.g., "if a proton were a marble, this atom would be a football stadium")
- the central [subject] has a prominent, glowing data panel that includes: size in 5 different unit systems (m, nm, å, light-seconds, planck lengths), aspect ratio, mass (if relevant).
- a special "scale cross-section" inset breaks the ring at one angular segment to show a linear zoom-in of the central subject's internal structure, from organelle down to atomic lattice.

contextual halo:
- a sweeping "you are here" indicator arrow points to the human scale (1.7 m) ring.
- cosmic and quantum boundaries are marked with dashed lines labelled "planck length (1.6 × 10⁻³⁵ m)" and "observable universe (8.8 × 10²⁶ m)".
- icons denoting measurement methods (optical microscope, x-ray crystal, gravitational lensing) sit near relevant scales.

lighting:
- central subject lit by an intense museum spotlight.
- all ring objects lit by a uniform, soft top-light so that their 3d forms are clearly readable; no dramatic shadows, as detail is paramount.
- the glass podium and rings have subtle light trapping and chromatic dispersion at edges.

title: "the cosmic zoom: where does [subject] fit in the 60 orders of magnitude?"
style: macro-photographic 3d miniature museum, editorial precision, with the gravitas of an eames office "powers of ten" infographic updated to current science.
