/**
 * Newsletter UI Styles
 * Used by: shared/newsletter-ui.js (popup modal + bottom-right toaster).
 *
 * THEMING NOTES FOR DESIGNERS
 * ---------------------------
 * This stylesheet reuses CSS custom properties from the **onboarding** app so
 * the popup matches that visual system. Each rule references the variable
 * with a hardcoded fallback, e.g.:
 *
 *     background: var(--lnn-ob-primary, #ff8217);
 *
 * Two ways to change a color/value:
 *
 *   1. Edit the **variable** site-wide (in the onboarding app) — affects this
 *      popup AND the onboarding modal.
 *
 *   2. Edit ONLY this popup — replace the `var(...)` reference with a plain
 *      value, OR scope an override on the popup's container, e.g.:
 *
 *          .newsos-nl-overlay,
 *          .newsos-nl-toaster {
 *              --lnn-ob-primary: #ff8217;
 *          }
 *
 * Class naming:
 *   .newsos-nl-overlay     — full-screen popup backdrop
 *   .newsos-nl-modal       — popup card (split layout, like onboarding)
 *   .newsos-nl-toaster     — bottom-right slide-up card
 *   .newsos-nl-content     — left column inside the modal (text + form)
 *   .newsos-nl-hero        — right column inside the modal (image)
 *   .newsos-nl-input       — email/name text inputs
 *   .newsos-nl-option      — single newsletter list as a checkbox row
 *   .newsos-nl-btn         — primary CTA button
 *   .newsos-nl-skip        — text-style "No thanks" / "Done" link
 *   .newsos-nl-dots        — step indicator (one filled, one hollow per step)
 *   .newsos-nl-msg         — inline success/error feedback
 *   .newsos-nl-close-x     — top-right ✕ on the popup modal
 *   .newsos-nl-close-btn   — top-right ✕ on the toaster
