/* service-areas.css — Greater Houston geo SEO landing pages.
 *
 * Loaded on /service-areas (index) and every /service-areas/<city> page.
 * Shares the design tokens, nav, footer, and accordion FAQ rules from
 * styles.css. Adds:
 *   • .sa-hero          — page hero shared across all geo pages
 *   • .sa-breadcrumb    — accessible breadcrumb trail at top of city pages
 *   • .sa-index-grid    — city-card grid on the /service-areas index page
 *   • .sa-card          — individual city card on the index
 *   • .sa-local         — "Why {City}" callout block (the unique paragraph)
 *   • .sa-services      — 3-column service rundown shared across pages
 *   • .sa-cases         — Houston-only case study highlights
 *   • .sa-how           — "How we work" 3-step block
 *
 * Houston hub uses every block; suburb pages skip .sa-cases and surface
 * the shared sections in a tighter cadence.
