Brainstorm approaches for: $@

Structure your answer as:
1. **Problem restatement** — one paragraph; what we're solving, what constraints matter, what "done" looks like
2. **Alternatives** — 3 to 5 distinct approaches. For each:
   - **Summary** — one or two sentences
   - **How it works** — the key mechanism
   - **Pros** — what it gets right
   - **Cons** — what it costs, risks, or breaks
   - **Best when** — the conditions that would make this the right pick
3. **Comparison table** — across the alternatives, score or rank on: complexity, time-to-ship, reversibility, performance, fit-with-existing-code
4. **Recommendation** — which one to pick *given the current codebase*, with the second choice as a fallback
5. **Unknowns** — questions that, if answered, would change the recommendation

Be opinionated. Surface real trade-offs, not strawmen. If the obvious approach wins decisively, say so and only enumerate 2 alternatives — don't manufacture options for the sake of a full set. If the problem is under-specified, ask clarifying questions before brainstorming.
