// Web e2e scenario: the Models settings page end to end through the real
// wire — the add card offers the dormant pi-ai catalog, typing an API key
// stores it write-only under the derived reference (`MINIMAX_CN_API_KEY`)
// while the settings document records only that reference, and the saved
// route registers live (the row's 已启用 badge is the topology invalidation
// landing). The customized-settings fold writes the curated reasoning field
// as a merge patch. Zero model calls: configuration is pure
// settings/credentials/llm-domain traffic, so there is no fixture and a
// stray stream would fail loud on the open seam. The provider under test is
// minimax-cn so a developer's real ANTHROPIC/OPENAI environment keys can
// never shadow the derived reference.
