 - Host er logget ind i Django.
 - Mindst én aktiv kategori med spørgsmål findes.
 
+## Cutover-forudsætning (`USE_SPA_UI`)
+- `USE_SPA_UI=false` (default): brug legacy routes `/lobby/ui/host` + `/lobby/ui/player`.
+- `USE_SPA_UI=true`: host må gerne testes på SPA deep-link route `/lobby/ui/host/<spa-path>` (fx `/lobby/ui/host/guess`), player på `/lobby/ui/player`.
+
 ## Flow
-1. Åbn host-siden på /lobby/ui/host og tryk Opret session.
-2. Åbn player-siden i 3 faner/enheder på /lobby/ui/player.
-3. Join alle spillere med sessionkode og nickname.
-4. Host: vælg kategori, Start runde, Vis spørgsmål.
-5. Spillere: brug round_question_id og submit løgn.
-6. Host: Mix svar.
-7. Spillere: submit gæt.
-8. Host: Beregn score og Vis scoreboard.
-9. Host: Næste runde eller Afslut spil.
+1. Verificér cutover-route matcher valgt flag (legacy vs SPA shell).
+2. Åbn host-siden og tryk Opret session.
+3. Åbn player-siden i 3 faner/enheder.
