**Dato:** 2025-11-17 Kodebasen har gjennomgått en omfattende refaktorering hvor reorder-funksjonalitet har blitt flyttet til dedikerte batch controllere: ### Nye Controllere - **`TaskBatchController`** (app/Http/Controllers/TaskBatchController.php) - Håndterer `POST /tasks/reorder` - `reorder()` metode (linje 14-67) - Oppdaterer task rekkefølge med parallel group støtte - `update()` metode (linje 72-214) - Batch oppdatering av tasks - **`ProjectBatchController`** (app/Http/Controllers/P...

Bytt ut custom implementasjon med Draggable.js for å oppnå: - 70-80% mindre kode - Bedre vedlikeholdsbarhet - Touch-støtte ut av boksen - Bedre animasjoner og UX

Prosjektet har for tiden ~600 linjer custom drag-and-drop kode spredt over flere filer. Dette skaper: - Vedlikeholdsutfordringer - Manglende touch-støtte - Cross-browser problemer - Duplisert kode

Denne planen beskriver trinnvis migrering fra custom JavaScript drag-and-drop implementasjon til Shopify Draggable.js biblioteket.
