Real-time shopping list with SSE sync between multiple clients, automatic item categorization using embedding-based classification + Bring icon matching, and card-based UI with category grouping. - SSE broadcast for live sync (add/check/remove items across tabs) - Hybrid categorizer: direct catalog lookup → category-scoped embedding search → per-category default icons, with DB caching - 388 Bring catalog icons matched via multilingual-e5-base embeddings - 170+ English→German icon aliases for reliable cross-language matching - Move cospend dashboard to /cospend/dash, /cospend redirects to list - Shopping icon on homepage links to /cospend/list
