Theme Name: Solar Co. — Wireframe Demo
Theme URI: https://phaseshift.example/demo
Author: Phaseshift
Author URI: https://phaseshift.example
Description: A low-fidelity grayscale wireframe of a generic solar-company homepage, used to pitch the Phaseshift Calculator plugin. Everything on the page is a gray placeholder — except the real, live calculator dropped into the center. The contrast shows a prospect exactly how the plugin would look embedded in their own site.
Version: 1.0.0

/* ============================================================
   Solar Co. — Wireframe Demo theme
   All classes are namespaced .swf-* so nothing collides with the
   calculator widget (which is scoped under .phsc-root).

   Design intent: a deliberately LOW-FIDELITY, monochrome mockup.
   No brand color appears anywhere on the page — the only colored,
   polished, working element is the live plugin in the center.
