/* ============================================================
   Shared Shore toolbar
   ------------------------------------------------------------
   The floating clay-dark toolbar used by the sculpting board and
   by every /projects/* page, so the whole site reads as one app.
   Pages own their own canvas/background styling; everything that
   makes the bar look and behave like Shore's lives here.

   Markup contract (see public/index.html for the canonical use):

     <div class="shore-toolbar" id="unified-toolbar">
       <div class="toolbar-drag-handle">⋮⋮</div>
       <div class="mode-buttons"><button class="mode-btn active">…</button></div>
       <button class="icon-button" id="fullscreen-button">⛶</button>
       <button class="icon-button" id="menu-button">☰</button>
     </div>
     <div class="dropdown-menu" id="menu-dropdown">…</div>

   Dropdowns are positioned by public/js/toolbar.js, not by CSS, so
   they can flip above/below the bar wherever it has been dragged.
