Theme Name: Personal Finance Command Center

Author: Finance Command Center
Author URI: https://example.invalid
Description: A calm, data-focused application shell for the Personal Finance Command Center plugin. Provides the sidebar, navigation, header, light/dark modes and design tokens. Contains no financial logic and no secrets; every financial screen is rendered by the companion plugin after server-side authentication. Remains usable as a plain theme if the plugin is inactive.
