/*
 * BROKEN EDITORIAL GRID — header, mobile navigation, footer, and the
 * header star. Ported from the approved prototype's header/nav/footer/
 * star rules (design-exploration/site-foundation/concept-1-broken-grid/
 * concept.css) onto real WordPress markup — class names match the
 * prototype directly wherever the underlying structure is the same, so
 * this reads as a direct port, not a re-styling. Every directional rule
 * uses logical properties, so Persian (RTL) and English (LTR) mirror
 * naturally.
 *
 * The homepage/archive/detail-page *compositions* are out of scope this
 * stage — see foundation.css and assets/css/public-content.css for what
 * already exists below the shell; neither is redesigned here.
