Context: Recipe suggestions are currently ranked by ingredient overlap count. A cross-encoder reranker can score "how well does this recipe fit my current pantry state + dietary profile" holistically, catching nuances that overlap counting misses (a recipe with 8/10 ingredients but one critical allergen should rank low; a recipe with 6/10 ingredients but perfect dietary fit should rank high).

Scope:

After initial recipe retrieval, rerank top-N candidates using (user_context, recipe_text) pairs
User context: pantry state, dietary restrictions, allergies, cuisine preferences
Wire to cf-core reranker service once available (see circuitforge-core ticket)
Especially valuable as community recipe library grows beyond a few hundred entries

Out of scope: Training a Kiwi-specific reranker (use general Qwen3-Reranker).

Acceptance criteria: Recipe feed order respects dietary constraints and pantry fit more accurately than overlap count alone.

Related: circuitforge-core reranker service (shared infrastructure).
