+## Key Learnings
+
+### Type System Patterns Established
+
+1. **Prisma Types:** Always use generated Prisma types for database models
+   - `import type { Post, Project, Media, Album } from '@prisma/client'`
+   - Use `Prisma.JsonValue` for JSON columns
+   - Use `Prisma.[Model]WhereInput` and `Prisma.[Model]UpdateInput`
+
+2. **Content Handling:** Create structured interfaces for complex nested data
+   - ContentNode interface for TipTap/BlockNote content
+   - Type guards for safe traversal (Array.isArray, typeof checks)
+
+3. **Component Types:** Use Svelte 5 and framework-specific types
+   - `Snippet` for render functions
+   - `Component` for component references
+   - Specific editor types (Editor, EditorView, JSONContent)
+
+4. **Error Handling:** Use type guards instead of `any` casts
+   - `err && typeof err === 'object' && 'status' in err`
+   - `Record<string, unknown>` for truly dynamic objects
+   - `unknown` instead of `any` when type is genuinely unknown
+
+### Commit Strategy
+
+- Commits grouped by logical batches (admin components, API routes, etc.)
+- Terse, informal commit messages focusing on impact
+- Frequent commits for easy rollback if needed
+- No mention of tooling (Claude Code) in commit messages
