-- external_components caches scraped catalog listings from supplier sites
-- (Regard, and later pg.pro/technosuccess.ru/DNS-shop) so the PC configurator
-- can offer just-in-time-sourced parts alongside the shop's own parts stock,
-- without hitting the supplier site on every picker render. Refreshed
-- periodically by internal/scraper, not written by any other code path.
