phase z slide_base + token CSS + families 갱신 (5-layer + F29 fix)

- templates/phase_z2/slide_base.html — geometry 재정상화:
  divider top 58 / height 2 / #cbd5e1
  body top 76 / height 585 / left 50 / width calc(100%-100px)
  footer left 50 / bottom 8 / height 41 / width calc(100%-100px)
  (사용자 lock 2026-05-07 — front 정합)
- templates/styles/tokens/{spacing,typography}.css — 5-layer 위계 lock 반영:
  spacing : --slide-divider-top 58 / --slide-body-top 76 / --slide-body-height 585 /
            --slide-footer-bottom 8 (slide_base.html 와 1:1)
  typography : --font-zone-title 16px (대) / --font-sub-title 12px (소) /
               --font-body 10px (콘텐츠) — 5-layer (대/중/소/부소/콘텐츠)
- templates/phase_z2/families/three_parallel_requirements.html — F13 partial:
  cleanup-1 (2026-05-08) stale 주석 정정 (Legacy templates/blocks/structures/
  prerequisites-3col.html reference 제거 — 해당 legacy 폴더 삭제 후 broken).
- templates/phase_z2/families/process_product_two_way.html — F29 partial:
  visual fidelity bug fix (2026-05-08).
  missing SVG asset 3 개 (header_left_bg, header_right_bg, body_bg) 참조 제거 →
  figma origin (figma_to_html_agent/blocks/1171281210/index.html) 의 R8 룰
  ("순수 CSS 우선") 따라 linear-gradient + border-radius pill 로 재현.
  PROMOTED 줄도 갱신 (banner-left/right bg gradient + body bg 2-half gradient).

regression 0 (MDX03 fresh run 검증 — final.html PASS, missing image 0).
