   - Always use `import { cn } from '@/utils/tailwindUtil'`
     - e.g. `<div :class="cn('text-node-component-header-icon', hasError && 'text-danger')" />`
   - Use `cn()` inline in the template when feasible instead of creating a `computed` to hold the value

+  - Find existing `!important` classes that are interfering with the styling and propose corrections of those instead.
