/* ============================================================
   COMPONENT: Eligibility Checker Page
   FILE: assets/css/eligibility-checker.css
   Phase: Stage 10.1 (Final Master Blueprint Roadmap, §16 —
   Utility Pages). Depends on: tokens.css, base.css, surfaces.css,
   forms.css, buttons.css. Owns only .checker-* selectors.
   Frontend-only step flow — assets/js/eligibility-checker.js
   toggles `.is-active` on one `.checker-step` / progress dot at a
   time; all steps are present in markup for no-JS/SEO fallback
   and progressively enhanced into a wizard.
   Bilingual/RTL: logical properties only.
