+-- MIGRATION: Remove Legacy items Column from user_top_lists
+-- ═══════════════════════════════════════════════════════════════════
+-- 
+-- This migration removes the deprecated items jsonb column from
+-- user_top_lists table. List items are now stored relationally in
+-- the user_top_list_items table.
+--
+-- SAFETY: Verified that no data exists in the items column and all
+-- code references use the relational user_top_list_items table.
+-- ═══════════════════════════════════════════════════════════════════
+
+-- Drop the legacy items column
+ALTER TABLE user_top_lists 
+  DROP COLUMN IF EXISTS items;
+
+-- Add comment to document the relational approach
+COMMENT ON TABLE user_top_list_items IS 'Stores list items relationally - replaces user_top_lists.items JSON column';
