Every calculation can be shared as a permanent URL. Click Share Result, get a link like mace-lake.vercel.app/r/gK7tabOE, and anyone can view the full result — 3D viewer, metrics, charts, export options — without logging in. Drawn molecules embed the 2D structure, SMILES, formula, and molecular weight directly in the shared page. Results are stored in Supabase with row-level security: once created, a shared result cannot be modified or deleted.
