 After updating to WordPress 7.0, the block editor
 shows a blank white page with this error:

 Uncaught TypeError: Cannot read properties of
 undefined (reading 'borderColor')
 at AIe (block-editor.min.js:178:89975)

 Theme: Blockify
 WordPress Version: 7.0
 PHP Version: (check yours in Site Health)

 The error occurs when WordPress 7.0 tries to read
 borderColor from a color palette item that doesn't
 have it defined. This breaks the block editor
 completely showing a blank white page.

 Steps to reproduce:
 1. Install Blockify theme
 2. Update to WordPress 7.0
 3. Go to Posts → Add New
 4. Editor shows blank white page with borderColor error
