@ -9,6 +9,7 @@ Bygge en løsning med to samtidige kortvisninger over samme positionsdata, hvor
 - Zoom og pan skal kunne ske uafhængigt i hvert kort
 - Visning skal være viewport-drevet, ikke bundet til et bestemt geografisk udsnit
 - UI'et skal beskytte læsbarheden, også ved meget store usikkerheder
+- Demoen skal køres via lokal webserver, ikke `file://`, fordi browser-adfærden ellers bliver upålidelig

 ## Funktionel plan

@ -78,6 +79,12 @@ Denne vurdering skal genberegnes:
 7. Teste zoom/pan og dynamiske overgange mellem inside/possible/outside
 8. Finjustere styling og læsbarhed

+## Erfaring fra implementeringen
+- Flere UI-problemer viste sig at hænge sammen med, at demoen blev åbnet via `file://` i stedet for en lokal webserver.
+- Zoom, pan og klik-relateret feedback opfører sig mere stabilt, når siden serveres via `http://127.0.0.1:4173/...`.
+- Derfor er lokal server nu en del af den forventede runtime for demoen.
+- Næste hovedskridt er stadig at gå fra ét kort til to samtidige kort med samme data og forskellige usikkerhedsperspektiver.
+
 ## Åbne designvalg
 - Om hjørneindikatorer skal ligge i et fast hjørne eller langs den nærmeste kant
 - Om store usikkerheder altid skal tegnes som cirkler på kortet, eller nogle gange kun repræsenteres via indikator
