/**
 * Common strengths, most common first, offered as chips when a medicine is
 * added. For picking only: the pack in her hand wins, and "Not sure" and
 * typing stay. A chip she picks is saved as the medicine's strength, which
 * the check reads, so a chip must never hide a dose the check could count
 * (tests/medicine-facts.test.ts runs the check on every chip).
 *
 * Single medicines are keyed by catalog ingredient. Products list the exact
 * catalog names whose packs they describe; another name of the same product
 * gets none of them ("Solpadeine" is not offered co-codamol's chips). A
 * single-ingredient product with no entry of its own uses its ingredient's
 * strengths. Herbal medicines have none: their strengths vary.
 *
 * Drafted from common UK and Nigerian packs and checked against DrugBank 5.1
 * products where it lists them. The pharmacist may correct any of them.
