/* =========================================================================
 * SchemaShift — Migration Safety Reviewer
 *
 * Shares the visual family of PyOptimize (serif + sans + mono pairing, glass
 * header, panel top-border gradient), with a teal accent to distinguish it
 * and a fourth severity tier ("critical") for blocking migration hazards.
 *
 * Accessibility decisions honoured (per accessibility-lead handoff):
 *   • Four-tier severity: text + border-style + colour. Critical uses a red
 *     tint AND a double-bold border style so forced-colors users never see
 *     critical and high collapse into each other.
 *   • Textarea: spellcheck=false + wrap=off are on the element itself;
 *     monospace font + tab-size here.
 *   • Rewrite phases use native <details>/<summary>; no JS keyboard logic.
 *   • Copy buttons are real <button>s with visible text.
 *   • Two-layer focus ring (outline + box-shadow).
 *   • prefers-reduced-motion disables hero shimmer + score transitions.
 *   • forced-colors: all decorative gradients collapse to system colours.
