KanbanTrait var tidligere bare en lenke til /board/[id]. Nå viser den
kolonner og kort direkte i BlockShell-panelet, med full funksjonalitet:

- Inline kanban-brett med kolonner (todo/in_progress/done) fra metadata
- Intern drag-and-drop mellom kolonner (status-edge oppdatering)
- Cross-panel drag: kort bruker setDragPayload for drag til andre paneler
- BlockReceiver: aksepterer drops fra chat/editor (innholdstransfer-modus)
- Opprett kort direkte i kolonne (inline input)
- Responsivt: kolonner stables vertikalt på smale paneler (@container + @media)
- accessToken-prop lagt til for mutasjoner

/board/[id]-ruten beholdes som frittstående visning.

+### KanbanTrait panel (oppgave 20.6, mars 2026)
+- **Inline panel:** KanbanTrait er nå et fullverdig BlockShell-panel som viser kolonner og kort direkte i panelet — ikke bare lenke til `/board/[id]`.
+- **Kolonner:** Henter kolonner fra `metadata.traits.kanban.columns`, fallback til `['todo', 'in_progress', 'done']`.
+- **Intern drag-and-drop:** Kort kan dras mellom kolonner for statusendring (bruker status-edge).
+- **BlockReceiver:** Aksepterer drops fra andre paneler (`innholdstransfer`-modus). Noder fra chat/editor opprettes som nye kort med `source_material`-edge.
+- **Drag-out:** Kort er draggable med `setDragPayload` — kan dras til andre paneler (chat, editor, kalender).
+- **Opprett kort:** Inline-knapp per kolonne for å opprette nye kort (tittel → content-node + belongs_to + status edges).
+- **Responsivt:** Kolonner stables vertikalt på smale paneler/mobil via `@container` og `@media` queries.
+- **Fullskjerm-toggle:** Via BlockShell-wrapperen (forelder-side wrapper KanbanTrait i BlockShell).
+- **`/board/[id]`-ruten beholdes** som frittstående fullside-visning for direktelenker.
+
 ### Gjenstår
 - Reposisjonering ved dra innad i kolonne (sortert rekkefølge)
 - Redigeringsmodal for kort (tittel/beskrivelse)
