/*
Theme Name: ETSS-EE Theme
Theme URI: https://etss.net
Author: Johann Peter Murmann
Author URI: https://professor-murmann.net
Description: A lightweight, secure, dependency-free shared theme for the two sister resource sites etss.net and economic-evolution.net. Classic two-column layout — left navigation, a reverse-chronological News feed, curated resource sections, and an Editor/Advisory Board column. All colours are set in the Customizer, so one theme serves both sites (blue/cream for ETSS, red/blue for Economic Evolution). Includes a built-in server-side contact form. No page builders, sliders or third-party plugins.
