/**
 * Replace the default empty mock with a populated one for dev mode + storybook.
 *
 * Call this from app boot when `USE_DEV_SEED=true`, mutually exclusive with
 * `bindProductionBlog(config)`. Tests must NOT call this — they construct
 * `new MockArticlesRepository()` directly and seed via factories per-test.
 *
 * Idempotent: safe to call multiple times; each call rebuilds a fresh
 * populated repo and rebinds the symbol.
