      <h1>SplitGrid examples</h1>
      <p>
        Drag any divider to resize — push-cascade kicks in once a neighbor hits its min.
        Double-click a divider to maximize the panel closer to the layout edge; double-click again to restore.
        Open the console for debug logs (on the IDE example).
      </p>
    </header>

    <main>
      <section>
        <h2>1. IDE-style layout</h2>
        <p class="note">
          Three panels with mixed units. Sidebar has bounds <code>240px</code> default,
          clamped to <code>160–400</code>. Middle is a nested column with an
          auto-fill editor (<code>min 120px</code>) and a <code>30%</code> console.
          Inspector starts at <code>20%</code> with <code>min 120px</code>.
          Debug logs are on for this one — exposed as <code>window.ide</code>.
        </p>
        <div class="example" id="example-ide"></div>
      </section>

      <section>
        <h2>2. Four panels, no constraints</h2>
        <p class="note">
          Every child is <code>auto</code> (<code>1fr</code>); no min or max.
          Panels can collapse all the way to <code>0</code> — useful for seeing the
          unconstrained default behavior.
        </p>
        <div class="example" id="example-fourfr"></div>
      </section>

      <section>
        <h2>3. Vertical (column) layout</h2>
        <p class="note">
          Top toolbar fixed at <code>56px</code>, main area takes the rest,
          bottom status bar fixed at <code>32px</code>.
        </p>
        <div class="example example--tall" id="example-vertical"></div>
      </section>

      <section>
        <h2>4. Deep nesting</h2>
        <p class="note">
          Row → column → row, three levels deep. Each container manages its own grid;
          dragging a divider only retracks its own container.
        </p>
        <div class="example example--tall" id="example-nested"></div>
      </section>

      <section>
        <h2>5. Custom resizer rendering</h2>
        <p class="note">
          The <code>resizer.render</code> hook receives the divider element so the
          consumer can style it freely. Here the divider is wider (<code>16px</code>),
          dark, and shows a grip glyph.
        </p>
        <div class="example example--short" id="example-custom-resizer"></div>
      </section>

      <section>
        <h2>6. Mixed units</h2>
        <p class="note">
          <code>200px</code> fixed + <code>auto</code> (fr) + <code>25%</code> +
          <code>auto</code>. Demonstrates that fixed-px tracks stay put on container
          resize while <code>auto</code> tracks absorb the change.
        </p>
        <div class="example" id="example-mixed"></div>
      </section>

      <section>
        <h2>7. Custom resizer via Vue slot</h2>
        <p class="note">
          Uses the <code>&lt;SplitGridView&gt;</code> <code>#resizer</code>
          scoped slot to render rich content inside each divider. Resizer
          track is <code>28px</code> wide (vs the <code>6–8px</code> default),
          and the slot receives <code>before</code> / <code>after</code>
          references to the adjacent panel definitions — used here to label
          each side. Drag still works because the slot content has
          <code>pointer-events: none</code>; the wrapper's drag wiring
          continues to own the actual resize gesture.
        </p>
        <div class="example example--short" id="example-vue-resizer"></div>
      </section>

      <section>
        <h2>8. Dynamic add/remove (Vue wrapper)</h2>
        <p class="note">
          Backed by <code>&lt;SplitGridView&gt;</code> from
          <code>@madronejs/splitpanel/vue</code>. The toolbar calls
          <code>addChild</code> / <code>removeChild</code> on the component ref;
          the <code>#leaf</code> scoped slot renders each panel's content
          (including its own close button). Vue's reactivity flows through
          <code>&lt;Teleport&gt;</code> into the leaf elements that SplitGrid
          manages.
        </p>
        <div class="example example--tall" id="example-dynamic"></div>
      </section>

      <section>
        <h2>9. Declarative tree (Vue components)</h2>
        <p class="note">
          The entire layout is written as
          <code>&lt;SplitPanel&gt;</code> / <code>&lt;SplitContainer&gt;</code>
          tags in the template — no imperative <code>addChild</code> calls.
          Adding / removing tabs is a plain
          <code>tabs.push(...)</code> / <code>filter(...)</code>;
          <code>v-if</code> toggles the console and inspector. Each panel's
          default slot is teleported into the SplitGrid-managed element, so
          contents move with the panels. Most panels have no
          <code>panel-id</code> — auto-generated from each component's uid.
        </p>
        <div class="example example--tall" id="example-declarative"></div>
      </section>

      <section>
        <h2>10. Drag-drop reorder</h2>
        <p class="note">
          Pointer-event-based drag-drop via <code>configureDraggable</code>.
          Grab a tile by its <code>⠿</code> handle and drop on another tile —
          the default <code>onDrop</code> calls <code>swapData</code>, so the
          tile contents swap while the slots stay anchored. Reactive flags
          <code>panel.isDragging</code> / <code>panel.isDropTarget</code> off
          the slot scope drive the visual feedback. A ghost element (cloned
          from the source) follows the cursor — anchor / custom renderer
          configurable via <code>ghostAnchor</code> and <code>ghostRender</code>.
        </p>
