/* ===========================================================================
 * Shared phosphor nav — case study pages
 *
 * The case-study layout (app/views/layouts/case_study.html.haml) loads only
 * the per-study stylesheet, not phosphor_page.css where the nav component
 * normally lives. This self-contained sheet provides the central nav
 * (shared/_phosphor_nav.haml) with the navy treatment used on the homepage,
 * and is linked only by the case-study layout. The homepage and inner
 * phosphor pages render the same partial styled from phosphor_page.css.
