/* =========================================
   Site boot gate and entry artifact contract
   =========================================
   This is the initial-load full/half entry artifact system.

   Purpose:
   - The loading screen is not decorative. It exists only during the first site entry in a
     tab, before the user is allowed into the normal wiki surface.
   - A "full" entry must mean that the first view of that system can appear without an
     additional visible data load. For the nations system, the 1950 entry is full only when
     its nation list/link-map data and first-view pixel decorations are ready in this tab.
   - A "half" entry is a predictive warm state for the next likely path. It may fetch and
     parse data, but may skip expensive final work such as image/canvas preparation until it
     is promoted to full.
   - This principle is a site-wide design priority, like SPA continuity. New viewers,
     document systems, and information panels should define their entry full/half packs
     before exposing a first screen that can visibly fill in later.
   - SPA navigation is a consumer phase, not a blocking phase.  Do not add BootGate holds
     to SPA route changes.  If a route needs seamless first paint, prepare its artifacts
     during the initial boot pack and have the subsystem consume EntryStore synchronously
     before inserting or painting visible DOM.

   Naming rule:
   - New public APIs, globals, classes, functions, files, and components must not use a
     project prefix. Old prefixed globals are legacy compatibility surfaces only.
   - New code should use names such as BootGate, EntryLoader, EntryStore, and boot-gate-*.

    /*
    Decoration semantic placement resolver
    -----------------------------------------
    장식 저장 데이터의 placement 값은 "사용자가 고른 의미상 위치"를 나타낸다.
    resolver는 그 의미값을 실제 DOM 부착 위치와 표시 조건으로 번역한다.

    예: 시대 문서에서 사용자가 1950년 / 아메리카를 지정하면 의미상 scope는
    그 조합이지만, 이미지를 붙일 기준면은 대륙 패널 자체가 아니라
    .clbi-nations-tabpanel-body이다. 따라서 placement=nations-continent-body는
    .clbi-nations-tabpanel-body에 이미지를 붙이고, 현재 활성 연도와 대륙이 저장값과
    일치할 때만 렌더링한다.

    유지보수 규칙:
    - 새 조합형 문서가 생기면 entry.target을 매번 특수하게 저장하지 말고 placement를 추가한다.
    - DevTools.js 에디터 미리보기와 Common.js 런타임 렌더러의 resolver는 같은 의미를 가져야 한다.
    - target은 물리적 기준면, era/continent 같은 필드는 표시 조건으로 다룬다.

    선언문은 실제 HTML과 ManifestoIntro의 실선 요소만 사용한다.
    이 구식 렌더러는 제목·본문과 완성형 구분선을 canvas에 한 번에 그려
    새 애니메이션의 선 뒤에 트랙이 나타날 수 있었다.

    기존 Common.js를 장기 캐시한 뒤 새 파일로 넘어오는 경우를 위해
    남아 있는 canvas와 상태만 제거하고 즉시 종료한다. 새 공개 이름에는
    프로젝트 접두사를 사용하지 않는 규칙을 유지한다.
