weights = skin-type vector × concern tilt × life-stage overlay, renormalized — the engine’s own
formula, run client-side on its real config vectors. it reproduces all four stored engine runs below to the 6th decimal.
dose lives one level up: in product analyses the engine turns each ingredient’s estimated concentration into risk/benefit scale factors. this page stays at the dossier level, where every number is stored engine output.
