/*
 * directory.css — Shared styles for all directory / locator pages
 * Extracted from inline <style> blocks duplicated across the 4 directory pages:
 *   - irs-office-locator.html
 *   - federal-reserve-directory.html
 *   - government-finance-directory.html
 *   - state-finance-offices.html
 *
 * Directory pages use a DIFFERENT design system from blog/calculator pages:
 *   - Sticky gradient header (not the inline brand header from common.css)
 *   - Full-width page hero with blue gradient
 *   - Dark footer variant
 *
 * Works alongside common.css which provides :root variables, box-sizing,
 * accessibility focus outlines, and img content-visibility.
 * Page-specific overrides remain in inline <style> blocks.
 *
 * Improves content-to-code ratio for Google AdSense compliance
 * and enables browser caching of directory-specific CSS.
