# T02: Replaced plain list rendering of related techniques with a responsive card grid showing title, creator name, category badge, and reason text

**Replaced plain list rendering of related techniques with a responsive card grid showing title, creator name, category badge, and reason text**

## What Happened

Updated the RelatedLinkItem TypeScript interface with creator_name, topic_category, and reason fields from T01's backend enrichment. Replaced the ul list in TechniquePage.tsx with a CSS grid of cards — each card shows the technique title as a link, creator name, topic category as a pill badge, and scoring reason. All fields conditionally rendered for graceful degradation. Added responsive grid CSS using existing design tokens: single column on mobile, two columns at 600px+.

## Verification

Frontend build passes with zero errors (48 modules, 743ms). grep confirms 6 related-card CSS rules and creator_name in the TypeScript interface. Backend tests require ub01 PostgreSQL — not runnable locally.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npm run build 2>&1 | tail -10` | 0 | ✅ pass | 2800ms |
| 2 | `grep -c 'related-card' frontend/src/App.css` | 0 | ✅ pass | 50ms |
| 3 | `grep -q 'creator_name' frontend/src/api/public-client.ts` | 0 | ✅ pass | 50ms |


## Deviations

None.

## Known Issues

Backend test suite cannot run locally — requires PostgreSQL on ub01:5433.
