/* ============================================================
   PANEL DESIGN SYSTEM (task #401)
   ------------------------------------------------------------
   Single source of truth for evidence-panel typography, spacing,
   cards, pills, CTAs, and stat blocks. Every renderer in
   evidencePanel.js follows the same skeleton:

     <article class="panel-content panel-{kind}">
       <header class="panel-header">
         <span class="panel-eyebrow">…</span>
         <button class="panel-close" data-act="close">×</button>
       </header>
       <h2 class="panel-title">…</h2>
       <p class="panel-subtitle">…</p>            (optional)
       <section class="panel-section">
         <h4 class="panel-section-label">…</h4>
         <p class="panel-body">…</p>
       </section>
       <div class="panel-cta-strip">
         <button class="panel-cta-primary">…</button>
         <button class="panel-cta-secondary">…</button>
       </div>
     </article>

   Loaded AFTER chat.css so these declarations win where they
   overlap with legacy renderer-specific selectors. Legacy
   classes (.insight-panel__title, .team-panel__name, etc.) are
   kept on the rendered nodes as a transitional aid for any
   third-party selectors, but the visual rhythm is owned here.

/* Heavy panel-content rules (padding/background/flex) are scoped to
   article.panel-content so the outer wrapper <div class="panel-content">
   stamped by renderCurrent / setStackedPanel / setWorkIndex / setEmpty
   doesn't double-pad when an inner article also carries the class.
   The bare `.panel-content` rule in chat.css (animation only) still
   applies to both the outer wrapper and inner article. */
