NIST SRD 69 covers thermophysical properties of ~74 fluids (Cp, viscosity, thermal conductivity, density vs T, P). US-government work, public domain in US per 17 U.S.C. §105 (foreign copyright may apply).
Action: scrape once for our gases.toml + liquids.toml entries (water, mineral_oil, glycerol, silicone_oil, N2, O2, Ar, He, Ne, Xe, CO2, methane, hydrogen, SF6). No public API — use the search interface. Cite as source = "nist:srd69" with the AS-IS / NIST notice in a top-level LICENSES-DATA.md.
