# Phase 8: WebAssembly 마이그레이션 - 기능 우선 아키텍처 (2026-07-03)
#
# DESIGN DECISION: prerender: false (not true)
#
# RATIONALE:
# - prerender: true = SSR (Server-Side Rendering) - 서버가 정적 HTML 미리 생성
# - InteractiveWebAssembly = CSR (Client-Side Rendering) - 클라이언트에서 동적 렌더링
# - These are contradictory: cannot prerender interactive WebAssembly content
#
# OBSERVED PROBLEM with prerender: true:
# 1. Unauthenticated users see prerendered HTML (no auth context)
# 2. AuthorizeRouteView renders nothing (authorized content cannot prerender)
# 3. After login, WebAssembly tries to render same component differently
# 4. Conflict: static prerendered HTML vs. dynamic WASM runtime
#
# SOLUTION: prerender: false
# - App boots to blank screen briefly (WebAssembly loading ~0.5-2s)
# - After load: all protected pages render correctly with auth
# - No conflicting render modes
# - Functional > Performance optimization
#
# See CLAUDE.md Phase 8 for architecture details.
