"""IMP-04 per-frame Jinja smoke harness (StrictUndefined).

scope-lock 16 조건 (Gitea #4) §11 / §13 :
  - smoke = isolated Jinja partial render with StrictUndefined
  - production render path (`phase_z2_pipeline.render_slide`) 미변경 — 본 harness 만 strict
  - builder output keys ↔ partial Jinja variables 정합 확인이 본 harness 의 목적
  - asset path / undefined variable / template syntax 실패 시 즉시 error

Usage :
  # sanity check existing frames (mock payloads bundled below)
  python scripts/smoke_frame_render.py --self-check

  # check a specific template with mock payload from stdin
  python scripts/smoke_frame_render.py three_parallel_requirements < mock.json

  # check all template_ids in `templates/phase_z2/families/` against bundled mocks
  python scripts/smoke_frame_render.py --self-check

Exit codes :
  0 = all renders succeeded (StrictUndefined passed)
  1 = at least one render failed
  2 = invalid input (template_id 미존재 등)

본 harness 는 IMP-04 의 per-frame 6-step gate Step 5 의 자동 실행 단위.
