/* R2 Funnel — email opt-in (R2-03) + 3-question quiz (R2-08).
 *
 * All new R2 funnel styles live in this single file so the email opt-in
 * (Stage 2 — newsletter capture) and the diagnostic quiz (Stage 3) ship
 * together without racing for lines in css/styles.css. Page-level CSS only
 * — no design-token redefinitions; we consume brand.css variables.
 *
 * Conventions:
 *   - Text on the dark navy panels uses var(--pulse-blue-400) (#5E9DE8),
 *     the R2-09 contrast-safe blue against navy-900.
 *   - Primary amber button uses navy text (R2-09 WCAG fix — amber-on-white
 *     and amber-on-navy with white text both fail 4.5:1).
 *   - Mobile breakpoint mirrors the rest of the site: 640px.
 *   - We deliberately avoid `display:none → display:flex` transitions; we
 *     toggle `[hidden]` (a11y) and use opacity for the visible state.
