Theme Name: Connecting H2O
Theme URI: https://www.connecting-h2o.com
Description: Child theme of Hello Elementor for the Connecting H2O storefront. Provides the brand design tokens, a coded header/footer (Elementor Free), and the base styling that the "Connecting H2O – Elements" widget pack builds on. Replaces the headless React/TanStack storefront so payments run natively through WooCommerce + Razorpay.
Author: Connecting H2O

/* Design tokens live in assets/tokens.css (enqueued before this file).
   This file holds base typography + the coded header / footer / sticky WhatsApp. */
