/**
 * nav-search.css - Expanding navbar search box
 *
 * The search box sits compact and visible by default. On focus (input or
 * submit button), it expands and overlays the nav items to its left rather
 * than pushing the rest of the navbar around. Pure CSS (:focus-within) --
 * no JS required, nothing to keep CSP-clean.
 *
 * The anchor keeps its small footprint in the flex flow at all times so
 * the right-side nav (user menu, dev badge) never shifts; only the form
 * inside it becomes absolutely positioned and grows leftward when focused.
