catalogue-sync은(는) 무엇을 하나요?
Use any time Claude Code touches the site's Pokémon card catalogue — server.js's /api/sets, /api/sets/:slug/cards, /api/cards/search routes, src/pages/Catalogue.jsx, src/data/eraMap.js, src/data/editions.js, or anything involving browsing/adding cards from PokeTrace's set/card list, era filters, set logos, or release-date sorting. Also use when asked whether the catalogue is "up to date" or "in sync" — it always is, by construction; there's no static file or rebuild step to check. Documents real gotchas found by hitting PokeTrace's and pokemontcg.io's live APIs that aren't mentioned in either's docs.
