Xanthophyll carotenoid — concentrated in retinal macula where it filters blue light + scavenges singlet oxygen. AREDS2 trial showed reduced progression to advanced age-related macular degeneration with lutein + zeaxanthin (replacing the unsafe-in-smokers β-carotene).

PK: THE STORED VOLUME WAS THE SOLVER DEFAULT WEARING A CITATION. 35 L is exactly 0.5 L/kg at the seventy-kilogram reference — the value resolvePk substitutes when the field is ABSENT — and this record cited abstract states no volume at all. Removing it is NUMERICALLY A NO-OP, since the resolver now supplies the identical number; what changes is that the record stops asserting a measurement it does not have, and the defaulted-volume lint begins counting it as the open gap it is. This is the batch-11 finding running backwards: there a deletion silently became a default, here a default had silently become a datum.
