Protein reduced model — PDB → RealQM → JSON

Enter a PDB ID, fetch from RCSB, parse atomic coordinates, run molecule.js to convergence, extract a reduced-model JSON. Defaults to chignolin (1UAO). Suggested small proteins: 1UAO (chignolin), 1L2Y (Trp-cage), 1VII (villin HP35), 1UBQ (ubiquitin), 2OOB (BPTI). For larger proteins, the box may be too small; adjust SCREEN below.
