### 2. Watch Replay Links ✅

**Link Format:** `/watch/replay?url=/replays/{match_id}.json.gz`

**Verified Links:**
- `/replays/m_test_6p_v1.json.gz`
- `/replays/m_test_close_v1.json.gz`
- `/replays/m_test_domination_v1.json.gz`
- All 8 match IDs are properly formatted in links

**Note:** Actual replay files are not yet present in `/data/replays/` (expected - match workers not run yet). Links are correctly formed and will work when replays are uploaded.

### 3. Curated Playlist Sections ✅

**Data Source:** `/data/playlists/index.json`
- **11 playlists** total

**Curated Playlists (best-of-week, biggest-upsets, closest-finishes):**
- ✅ "Best of the Week" - 8 matches
- ✅ "Biggest Upsets" - 1 match
- ✅ "Closest Finishes" - 2 matches
- ✅ "Best Comebacks" - 1 match
- ✅ "Marathon Matches" - 2 matches
- ✅ "Domination" - 1 match
- ✅ "Season Highlights" - 3 matches
- ✅ "Featured Matches" - 8 matches

**Empty State Handling:**
- ✅ "Evolution Breakthroughs" - 0 matches (shows gracefully)
- ✅ "Rivalry Classics" - 0 matches (shows gracefully)
- ✅ "New Bot Debuts" - 0 matches (shows gracefully)

**Playlist Display:**
- 3 curated sections displayed prominently at top
- Horizontal scrolling row for additional playlists
- Category badges (Featured, Upsets, Comebacks, etc.)
- Match counts displayed

### 4. Thumbnails (Known Issue - R2) ⚠️

**Status:** Expected to 404 - R2 thumbnail upload is broken (ESO credentials issue)

**Thumbnail URL Format:** `https://r2.aicodebattle.com/thumbnails/{match_id}.png`

**UI Behavior:**
- ✅ Match cards render cleanly without thumbnails
- ✅ No broken image icons visible
- ✅ Layout handles missing thumbnails gracefully
- ✅ "Narrated" badge indicates enriched matches instead of thumbnail

**Note:** When R2 is seeded with thumbnails, they will automatically appear. Current implementation handles the absence correctly.

### 5. Pagination / Infinite Scroll ✅

**Implementation:**
- Initial batch: 20 matches
- Lazy-loading via IntersectionObserver
- "Show more" button for manual loading
- Batch size: 50 matches per load

**Current State:**
- 8 total matches (below initial 20 threshold)
- All matches displayed immediately
- Infrastructure in place for pagination when match count grows

**Mobile Browser Testing (Pixel 6 via ADB):**
- ✅ Layout not broken
- ✅ Text readable
- ✅ Touch targets usable (bottom tab bar navigation)
- ✅ No horizontal overflow
- ✅ Smooth scrolling
- ✅ Playlist cards horizontally scrollable
