/*
 * Eleos CASA — recruitment landing page
 *
 * Design system inspired by the CASA national identity and grandprairiecasa.org.
 * Lenses applied:
 *  - Visual hierarchy: one primary CTA per section, generous scale on H1/H2
 *  - F-pattern scanning: eyebrow → headline → subhead → CTA in the hero
 *  - Trust & accessibility (WCAG POUR): contrast >= 4.5:1, visible focus rings,
 *    skip link, semantic landmarks
 *  - Fitts's law: 48px+ tap targets, block CTA on mobile signup
 *  - Mobile-first: base styles assume 390px; breakpoints expand upward
 *  - Plain language: typography supports long-form clarity, not decoration
