/*
 * THEME TOGGLE
 * Sun/moon switch in the navbar (public/nav-actions). Linked directly in
 * layout.html rather than @import'd through style.css — style.css's legacy
 * duplicate block sits after its own @import aggregator in source order, so
 * an @import'd rule loses any specificity tie to it. A direct <link> placed
 * after style.css's <link> avoids that entirely.
