Vivarium is a static site with no backend, no accounts, and no data collection — a saved world JSON never leaves your machine unless you share it.

• Report issues with the save/load format or a page that runs unexpectedly heavy scripts through GitHub private vulnerability reporting. Include the seed, steps, and browser version.
• Do not post anything sensitive in issues. Worlds contain no personal data, but redact file paths if you paste console output.
• Supported release: the latest main.
