/**
 * File: assets/css/mln-checkout.css
 * Purpose: [mln_checkout] signup form + [mln_confirmation] receipt styling on
 *          /membership-registration/. Stripe Elements card field + grouped
 *          form sections (Account / Billing / Mailing / Membership & Referrer /
 *          Payment / Order summary) + discount code + order summary panel.
 *
 *          This surface ALSO hosts the embedded referrer/region/hub block
 *          (MLN_Registration_Service::render_referrer_block_html) and the
 *          mailing-address block (MLN_Mailing_Address::render_form_fields).
 *          Those emit the .mln-* / .mln-referrer-* / .mln-input family but are
 *          NOT wrapped in .mln-registration-wrap here — so this file styles
 *          that family scoped under .mln-checkout (the free-tier registration
 *          page reuses the same classes under .mln-registration-wrap, styled in
 *          mln-registration.css).
 *
 * Design system: consumes assets/css/mln-design-tokens.css custom properties
 *   (var(--mln-*)). Accent = MLN blue #004AAD. Lexend headings / Source Sans 3
 *   body. No hard-coded one-off colors/spacing — tokens only. (F-Chad-021)
 *
 * V-gates covered:
 *   - V-FRONT-002 (Stripe Elements card field renders + client-side validation)
 *   - V-FRONT-006 (responsive at 320 / 768 / 1280, no fixed px widths)
 *   - V-FRONT-007 (44x44px min tap targets)
 *   - V-FRONT-008 (no card data in engine PHP — Stripe iframe styled via
 *                  .StripeElement classes only)
 *   - V-FRONT-009 (inline error messages, no alert())
 *
 * LOAD-BEARING (JS-bound / contract — styled, never renamed):
 *   .mln-checkout, .mln-checkout__form, .mln-checkout__stripe-host (#mln-stripe-host),
 *   .mln-checkout__stripe-error, .mln-checkout__submit, .mln-checkout__discount-input,
 *   .mln-checkout__discount-apply, .mln-checkout__discount-feedback,
 *   .mln-checkout__form-error, .mln-checkout__form-success,
 *   .mln-checkout__summary-row--discount, [data-mln-region], [data-mln-summary].
 *   Referrer/hub/mailing: #hub_region, #hub_id, #referrer_search,
 *   #referrer_search_results, #referrer_dropdown_toggle, .mln-referrer-dropdown,
 *   .mln-referrer-result, .mln-referrer-name, .mln-referrer-email, .mln-input,
 *   .mln-form-field, .mln-cols-2, .mln-radio-option, .mln-dropdown-toggle.
 *
 * Loaded by: MLN_Checkout::enqueue_assets() — depends on mln-design-tokens
 *            + mln-fonts handles.
 *
 * @package MLN_MLM_Engine
 * @since   2.0.0
 * Version: 3.0.0
 * Changelog:
 *   3.0.0 — 2026-06-02 — MLN UI overhaul Wave 1. Full rewrite onto the design
 *           token layer (var(--mln-*)): Lexend/Source Sans 3 typography, MLN
 *           blue accent, card surfaces for sections + order summary + payment,
 *           visible focus rings (--mln-focus), 44px tap targets, mobile-first
 *           320/768/1280 with no fixed px widths, 200ms transitions with
 *           prefers-reduced-motion honored via the token. Added scoped styling
 *           for the embedded referrer/hub/mailing .mln-* family (which renders
 *           inside .mln-checkout, NOT .mln-registration-wrap) — referrer
 *           results are now a clean scrollable bordered dropdown (max-height +
 *           overflow-auto, hover/active rows, name over muted email).
 *           Presentation only — zero behavior / id / name / class changes.
 *   2.x   — pre-overhaul WP-admin palette (#2271b1) hard-coded. Superseded.
