/* ─────────────────────────────────────────────────────────────
   BCI Settings Modal — shared styles for the per-game settings
   modal that every game uses.

   This is a pure stylesheet — no JS. Each game still owns its
   own modal markup + JS wiring, but the visual presentation
   (panel, sliders, click-toggle rows, reset button) lives here
   so all games stay in lockstep on the look-and-feel.

   Required theme tokens (set in each game's :root or a global
   stylesheet):
     --bg-card, --border, --border-strong
     --text-primary, --text-muted, --text-dim
     --click-blue, --click-orange   (used by sliders + reset hover)

   Required markup shape:
     <div class="modal">
       <div class="modal-panel">
         <div class="modal-header">
           <div class="modal-title">…</div>
           <button class="modal-close">…</button>
         </div>
         <div class="settings-section">
           <div class="settings-label">…</div>
           <div class="settings-desc">…</div>   <!-- optional -->
           <div class="slider-top">
             <span class="slider-range">…</span>
             <span class="slider-value">…</span>
           </div>
           <input type="range" …>
         </div>
         <div class="settings-section">
           <div class="click-toggle-row">
             <div class="click-dot"></div>
             <span class="click-name">…</span>
             <input type="checkbox">
           </div>
           …
         </div>
         <div class="settings-footer">
           <span class="settings-note">…</span>
           <button class="settings-reset">Reset</button>
         </div>
       </div>
     </div>
