/* ==========================================================================
   Panel — Side Panel / Slide-Over
   Third member of the overlay family: dialog (blocks), sheet (slides up),
   panel (slides from right, coexists with main content).

   Desktop (≥769px): fixed right overlay, configurable width.
   Mobile (<769px): full-screen slide from right (blocking overlay).

   Focus model:
     Desktop — focus moves to panel, NO trap. Both regions interactive.
     Mobile  — focus trap enabled (panel is full-screen, main hidden).
   Panels are parallel content, not blocking content. Trapping focus on
   desktop would break the UX for keyboard users who need to reference
   the main content. At mobile, the panel goes full-screen — the user can
   no longer see the main content, so the interaction model changes.

   Usage:
     <div class="sui-panel" id="myPanel" aria-label="Detail" aria-hidden="true">
       <div class="sui-panel-header">
         <span class="sui-panel-title">Contact</span>
         <button class="sui-panel-close sui-btn sui-btn-ghost sui-btn-sm"
                 aria-label="Close panel" type="button">✕</button>
       </div>
       <div class="sui-panel-body">…</div>
       <div class="sui-panel-footer">…</div>
