Snippet Name: Persistent Toast
Description: Toast that stays open until explicitly dismissed, with a shrinking progress bar showing the remaining time. Great for upload/download progress or important notices.
Author: DevSnips Contributors
Usage Example: Call showToast() for a non-ignorable confirmation that still times out.
