Interactive Standard Model from quarks to the periodic table. Six discrete scale tiers — quarks, nucleons, nuclei, atoms, molecules, elements — with electron-cloud rendering and ball-and-stick molecular models.

Curated reference loci — HBB, LCT, BRCA1, ACE2, TP53. 5′→3′ codon ribbon with annotated regions, codon→amino-acid translation, and ambient B-form double-helix render. AI commentary in subsequent phases.

Periodic table explorer, molecular builder with Lewis structures, reaction simulator with balanced equations, and thermodynamics calculator.
