feat(skill): absorb external design skills, restore interview gate, add review route

- Restore the step-0 interview as a mechanical gate the skill explicitly depends on; add harness.md (per-harness question tools, limits, fallbacks) and brief-interview.md (slots, question cards, rounds). - Add 10 reference docs absorbed from external design skills (accessibility, interaction-feel, elevation, color, icons, product-copy, component-systems, critique, change-review, print-email) and extend existing references. - Add a review-only route and two hard-gate clauses (truncated content reachability, three-flashes limit). - design-gate: split tap targets into WCAG 2.5.8 and 44px contract layers, run axe-core when available, and fix false positives found on a real site (decorative alt="", stacked wordmark line count, url-only pages). - lint-skill: fail if the interview gate section or its links disappear. - Ship agents/openai.yaml and THIRD_PARTY_NOTICES.md.

+# THIRD_PARTY_NOTICES.md — 외부 스킬 참고 고지
+
+designpaca 스킬 문서(`packages/skill/references/*.md`)는 2026-09-24 작업에서 외부 디자인 스킬 10종과 그 의존물(better-interface의 자매 스킬 7종 포함)의 절차·수치 시작값을 참고해 **번역·재서술**했다. 원문을 그대로 붙여 넣은 곳은 없다. 코드 스니펫이나 구체적 수치를 그대로 옮긴 자리는 본문에 대괄호 출처 ID(예: `[SKILL-APPLE-DESIGN]`)를 달아 표시했으며, ID별 상세(지지하는 주장, 적용 조건, 잘못된 일반화)는 [references/evidence-ledger.md](references/evidence-ledger.md)의 "외부 스킬 출처" 절에 있다.
+
+이 고지의 목적은 두 가지다. 첫째, MIT·Apache-2.0 원본의 저작권 고지·허가 고지를 보존한다. 둘째, Apache-2.0 원본에 대해 재서술 사실과 변경 내용을 밝힌다. MIT와 Apache-2.0은 모두 재사용·수정·재배포·상업적 이용을 허용하며, 조건은 저작권 고지 보존(MIT)과 NOTICE·변경 고지(Apache-2.0)뿐이다.

+better-interface와 자매 7종(better-accessibility, better-colors, better-layout, better-typography, better-ui, better-writing, interface-review)은 같은 저장소 `jakubkrehel/skills`의 저장소 루트 LICENSE 하나로 전부 커버된다.
+
+## 2. Apache-2.0 원본의 NOTICE와 변경 고지
+
+### frontend-design (anthropics/skills)
+
+저장소 루트에는 LICENSE 파일이 없고, 스킬 디렉터리 안에 `skills/frontend-design/LICENSE.txt`(Apache License 2.0 전문)가 있다. `anthropics/skills` README도 "이 저장소의 많은 스킬이 오픈소스(Apache 2.0)"라고 밝히고 `docx`·`pdf`·`pptx`·`xlsx`만 source-available 예외로 든다. 저장소 루트에는 별도의 `THIRD_PARTY_NOTICES.md`가 있으나, 그 내용은 `docx`/`pdf` 등 다른 스킬이 번들하는 바이너리 의존물(imageio, FFmpeg 등)에 대한 것이라 `frontend-design`과 무관해 여기 옮기지 않는다.
+
+**변경 고지**: designpaca는 `frontend-design`의 제네릭 클러스터 점검표와 반사실 검증 절차를 재서술·번역했으며 원문을 그대로 싣지 않았다. 구체적 예시(hex 값 등)는 [antipatterns.md](references/antipatterns.md)에 출처 ID `[SKILL-FRONTEND-DESIGN]`으로 표시했다.
+
+### adapt / impeccable (pbakaus/impeccable)
+
+저장소 루트에 Apache License 2.0 전문과 별도 `NOTICE.md`가 있다. `NOTICE.md` 원문은 다음과 같다.
+
+```
+# Third-Party Notices
+
+This project includes content derived from third-party work, used under the terms of its original license.
+
+## Platform Design Skills
+
+The `skill/reference/ios.md` and `skill/reference/android.md` platform reference files are distilled from ehmo's `platform-design-skills` (Apple Human Interface Guidelines and Material Design 3 rules), rewritten in Impeccable's voice.
+
+**Original work:** https://github.com/ehmo/platform-design-skills
+**Original license:** MIT
+**Author:** ehmo
+```
+
+designpaca가 참고한 것은 `skill/reference/adapt.md`(pointer·hover 쿼리, 컨테이너 쿼리, 커스텀 컨트롤 제스처 검증 절차)이며, 위 NOTICE가 가리키는 `ios.md`/`android.md`(ehmo의 `platform-design-skills` 파생물)는 이번 작업에서 참고하지 않았다. 그래도 Apache-2.0 원본의 NOTICE 전체를 투명하게 남기기 위해 그대로 옮겼다.
+
+**변경 고지**: designpaca는 `adapt.md`의 입력 방식 감지·제스처 검증 절차를 재서술·번역했으며 원문을 그대로 싣지 않았다. 코드 스니펫은 출처 ID `[SKILL-IMPECCABLE]`로 표시했다.

+
+각 스킬에서 재서술한 구체 규칙·수치는 본문에 해당 출처 ID(`[SKILL-APPLE-DESIGN]`, `[SKILL-BETTER-UI]` 등)로 표시했으며, 원문 문장을 그대로 복사한 곳은 없다.
