/**
 * File: sections.css
 * Purpose: Content section styling (about, features, services, benefits, maps/iframe placeholders) including
 *          responsive grids and interactive hover states.
 * Guidelines: Keep structural grids semantic; reuse tokens from variables.css; minimize deep selector chains.
