Resizable Container lets users manually change the width of one container with a vertical drag handle. It updates the container width within the parent bounds and emits the new width.
Use it for a resizable preview pane, editor canvas, inspector or detail panel, side content area, responsive demo area, chart preview, or docs playground.
Do not use it for split layouts between two panels, image resizing, table column resizing, or normal responsive containers that should resize automatically.
Key Features:
- Width resizing through a right-side drag handle.
- Minimum width constraint.
- resized event with the current width.
- Works with arbitrary content inside the container.
