MANUAL_CURATION
via MIM curation (#260)
Created to cover a CultureMech label MIM could not resolve (#260): Reasoner & Geldreich's low-nutrient agar for heterotrophic plate counts. A named medium, but MICRO has the class, so §3 step 1 grounds it rather than minting — matching `Brucella agar` (MICRO:0000595) and `Bacto Tryptic Soy Agar` (MICRO:0000114). MICRO:0000541 'R2A medium' is the broth; this label says agar. Cross-reference: CultureMech:002706 (data/normalized_yaml/bacterial/r2a_agar.yaml).

The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).
