Review summary

Change summary

Two files modified, both in the web app's page-level components:

1. apps/web/app/page.tsx (unstaged) — Wraps the "Trending" SectionCard in a {trending.length > 0 && (...)} guard so the section is hidden when the array is empty rather than rendering an empty card.

2. apps/web/app/feed/page.tsx (committed on branch) — Adds a new "Groups / Your circles" section to the feed, gated with groups.length > 0. Also fetches groups via repository.listGroups(viewerHandle). This is unrelated to the stated objective but ships on the same branch.

Validation confidence: Medium-High

• The trending guard is correct and minimal — length > 0 is the right check.
• No .slice() was added to trending.map(...), meaning when 1-2 items exist the section still renders (correct — the objective is about fewer than 3, not exactly 3).
• The "Feed preview" section above it has no equivalent guard, so a fully empty feed still renders an empty card — out of scope but worth noting for consistency.

Remaining risks

Verdict: The core fix is sound — stage and commit the page.tsx change before merging. Consider adding a minimal test and splitting the unrelated groups work into its own PR.
