Improve core performance

**Problem**
When working with components, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or entry points. Start by locating the component error-handling paths in the repository and review how their current messages are produced. Done means the relevant errors provide more descriptive debugging information, with tests covering the updated behavior.
