/* ═══════════════════════════════════════════════════════════════════════════
 * FairyAurora v4.0 — fa-modal canonical shell
 *
 * Single shell with three modes (confirm / settings / wizard) and four tone
 * modifiers (neutral / danger / warning / success). Spec at
 * docs/design_system/sections/modals.html.
 *
 * Shell structure (BEM):
 *   .fa-modal                       — fixed-positioned shell + backdrop combined
 *   .fa-modal--confirm              — destructive / approval mode
 *   .fa-modal--settings             — preference / configuration mode
 *   .fa-modal--wizard               — multi-step mode (legacy rules live in fairy-aurora-components.css)
 *   .fa-modal--danger|warning|success|neutral  — tone modifiers
 *   .fa-modal.is-open               — open state
 *     ├ .fa-modal__backdrop         — click-out close target
 *     └ .fa-modal__container        — actual dialog box
 *         ├ .fa-modal__header
 *         │   ├ .fa-modal__icon
 *         │   ├ .fa-modal__heading
 *         │   │   ├ .fa-modal__title
 *         │   │   └ .fa-modal__sub
 *         │   └ .fa-modal__close
 *         ├ .fa-modal__body
 *         │   ├ .fa-modal__message
 *         │   ├ .fa-modal__diff > .fa-modal__diff-row
 *         │   └ .fa-modal__field > .fa-modal__field-hint, .fa-modal__field-input
 *         └ .fa-modal__footer
 *
 * BC note: existing .fa-modal--wizard rules (fairy-aurora-components.css ~8369-8740)
 * remain unchanged; wizard mode renders inline (not as a fixed-position shell)
 * for the design-system live-preview case. New wizard adoptions wrap the macro
 * in a .fa-modal--confirm-like shell pattern (see _gdpr_breach_wizard_modal.html.twig).
