// Characterization of the providers.ts catalog split (god-file decomposition): the host became a
// barrel that re-exports 10 data catalogs now living under constants/providers/*, and APIKEY is
// merged from 6 semantic family files (apikey/<family>.ts). Locks: the public surface (every catalog
// + helpers still exported), the spread-merge integrity (166 APIKEY entries, no loss/dup), and that
// load-time Zod validation still runs. Pure-data move → behavior must be identical.
