Full design-team suite: `tests/design-team/ -q --tb=no` → **10 passed**, no other tests in directory; no regressions introduced.

## 3. L1 PNG Generation

Command:
```
python3 /home/jay/workspace/skills/mobile-prototype-ko/scripts/render_prototype.py \
  --device iphone15pro --mode light --scenario dashboard \
  --output /home/jay/workspace/skills/mobile-prototype-ko/outputs/dashboard_iphone15pro_light.png
```

Output: `OK: /home/jay/workspace/skills/mobile-prototype-ko/outputs/dashboard_iphone15pro_light.png`
File size: 183,819 bytes (≈ 180 KB) — far above the 5 KB acceptance criterion.

## 4. Compliance Notes

- **Frontmatter:** SKILL.md begins with `---\nname: mobile-prototype-ko\ndescription: ...\n---`
- **No external API URLs** in render_prototype.py / validate_korean_ocr.py (verified by `test_no_external_api_direct_calls`)
- **frontend-design** read-only — no modifications to that skill or any blocked path
- **Korean fonts:** `Pretendard, "Noto Sans KR", -apple-system, sans-serif` declared in every frame and scenario
- **word-break: keep-all** applied to body in all frame + scenario files
- **Dark/Light mode** both have AAA-grade contrast (#0a0a0a on #ffffff for light, #f4f4f6 on #0a0a0a for dark)
- **Status bar:** all 4 frames carry "9:41" + signal/wifi/battery glyphs (white on dark, black on light)
- **Dynamic Island:** 120×35 px, top:11 px, border-radius:17 px (iPhone variants)
- **Hole punch:** 24 px circle, top:14 px, centered (Pixel variants)

## 5. Issues / Decisions

- The user spec said "5 scenarios" in some places and "7 scenarios" elsewhere; implemented all 7 (signup_step1/2/3 + dashboard + insurance_compare + cardnews_publish + ai_analysis) as the full enumeration requires. The test `test_all_5_scenarios_exist_with_korean` was renamed in spirit (still uses that exact name to match the user's required test name) but iterates all 7 scenario files.
- pytesseract is not validated end-to-end here because the spec only mandates that the script imports cleanly and exits with 2 on missing deps (already covered).
- The render script ignores the `--mode` checkbox arg by simply selecting the matching frame HTML — frames already encode the mode-specific colors / glyph fills.
