* Loads the optional peer dependency `emoji-picker-element-data` and adapts its JSON export into
* this component's own `EmojiPickerGroup[]` shape via `adaptEmojiPickerElementData()` below. Never
* throws — resolves `null` (with a one-time `console.warn`) if the peer isn't installed, the import
* otherwise fails, or the resolved module matches neither the expected bare-array nor
* `{ default: [...] }` namespace shape (a broken or spoofed peer) — that last case fails closed
* rather than silently folding into `[]`, which would be indistinguishable from a well-formed peer
* that legitimately produced zero groups. Mirrors `pdf-loader.ts`'s `loadPdfJsDeps()` exact shape.
* `importData` is an injectable seam for tests (see `emoji-data-loader.test.ts`).
