How Multi-Select Works 🎯

Single Selection

// Click element → Single select
onElementSelected(elementId, event)
  if (!event.ctrlKey && !event.metaKey) {
    selectedElementIds.set([elementId]);
  }

Multi-Selection

// Ctrl+Click → Add/Remove from selection
if (event.ctrlKey || event.metaKey) {
  if (selected.includes(id)) {
    // Deselect
    selected = selected.filter(x => x !== id);
  } else {
    // Add to selection
    selected = [...selected, id];
  }
}

Operations on Multiple Elements

How Shape Scaling Works 🔧

The SVG viewBox Magic

Key Concept: Separate viewBox (internal coords) from width/height (display size)

<!-- Original element -->
<svg viewBox="0 0 100 100" width="100" height="100">
  <circle cx="50" cy="50" r="40" />
</svg>

<!-- After resize to 200×200 -->
<svg viewBox="0 0 100 100" width="200" height="200">
  <circle cx="50" cy="50" r="40" />  <!-- Same coordinates! -->
</svg>
