Restore Old Admin Colors

WordPress 7.0 changed the default admin color scheme to “Modern”, renaming the long-standing classic palette to “Fresh” and migrated existing users over to the new default. This plugin restores the classic Fresh scheme for users who are still on the Modern default or have no saved preference, without taking away anyone’s freedom to switch back later.

• Sets the color scheme to Fresh for newly registered users.
• Migrates each existing user from “Modern” (or no preference) back to “Fresh” the next time they visit the dashboard, exactly once.
• Leaves users who already chose another scheme (Light, Blue, Midnight, Ocean, Coffee, Ectoplasm, Sunrise, etc.) alone.
• Restores the classic “Fresh” look on the login screen too: the blue WordPress logo, the classic blue submit button, and the classic blue input focus ring.
• Records when each user has been processed, and records the previous color value only when the plugin changes that user.
• Adds a GoalPrevail admin dashboard/overview page. The plugin has no configurable settings page because it works automatically.
• No public front-end assets, no scheduled jobs, and no mass updates on activation. The login styles are printed only while the plugin is active and disappear the moment it is deactivated or deleted.
