Module components/MoleculeSpinner

What a MoleculeSpinner resolved, reported through MoleculeSpinnerProps.onStatusChange. Everything but state is present only once a structure has been drawn.

Props for MoleculeSpinner.

• query - The search query to depict. Changing it resolves a new structure.
• size - Canvas edge length in CSS pixels. Defaults to 128, matching the cube it replaces.
• spinSeconds - Seconds per revolution. Changing it retimes without rebuilding.
• atomScale - Multiplier on the uniform atom radius; lower is more stick, less ball.
• showHydrogens - Draw explicit hydrogens. On by default; the full structure reads better than a bare skeleton.
• pending - Rendered while the structure is still being resolved, before anything is known. Kept separate from fallback so callers never flash one graphic and then replace it with another.
• fallback - Rendered only once it is settled that there is nothing to draw: no query, no PubChem match, or no usable WebGL context.
• onStatusChange - Notified on every lifecycle transition.

Where a MoleculeSpinner is in its resolve-and-render lifecycle.

Renders the molecule a search query refers to as a slowly rotating ball-and-stick model, as a drop-in replacement for a generic loading spinner.
