What to build

Replace per-request homepage recommendation recomputation with a cheaper path based on precomputation and caching. Anonymous homepage traffic should not force full-material candidate loading and full Python scoring on every request. The recommendation experience can remain useful while using bounded candidate sets and cached outputs.

Acceptance criteria

• Anonymous homepage recommendations are served from a precomputed or cached result instead of being recomputed on every request.
• Recommendation freshness and correctness remain acceptable for the homepage experience.
• The implementation defines cache invalidation or refresh cadence clearly enough for maintainers to operate it.
• Verification compares the before/after cost of serving repeated anonymous homepage visits.
