/*
Theme Name: Aperture
Theme URI: https://example.com
Author: Custom Build
Description: A fast, multipurpose WordPress theme built from native Gutenberg blocks — no page-builder plugin required. Flexible sections, lean header/footer, theme options via the Customizer. Blog and WooCommerce are intentionally separate, optional plugins so a site that doesn't need them never loads their weight.
Version: 1.0.0
Requires at least: 6.0
Requires PHP: 7.4
Text Domain: aperture
