# Phase 9: 어드민 페이지별 렌더모드 정상화 (2026-07-03)
#
# DESIGN: Router/Routes에는 렌더모드를 지정하지 않고, 페이지별로 개별 지정한다.
#
# RATIONALE:
# - Blazor Web App은 "전역 렌더모드"와 "페이지별 렌더모드" 중 하나만 선택할 수 있다.
# - Router/Routes에 @rendermode를 지정하면 하위 모든 페이지의 개별 @rendermode는 무시된다.
# - 로그인만 prerender: true가 필요하고(흰 화면 방지), 나머지 [Authorize] 페이지는
#   prerender: false가 필요하다(인증 컨텍스트 없이 prerender 시 AuthorizeRouteView가
#   빈 화면을 그리는 문제를 피하기 위함). 이 둘을 동시에 만족하려면 전역 지정을 버리고
#   페이지별 지정으로 가야 한다.
#
# See CLAUDE.md Phase 9 for architecture details.
