Small browser experiments by ZirkoMirko. Each one is plain static files, so there's no build step. The site mirrors this layout: projects/<slug>/ here is zirkomirko.com/fun/projects/<slug>/ there. Play with them at zirkomirko.com/fun/projects.

Run one locally

Serve the project folder with any static server, for example:

cd projects/write-in-stars
python -m http.server 8000

Then open http://localhost:8000.

Before committing

Install the local secret hook once per clone: git config --local core.hooksPath .githooks.

Run python tools/scan_secrets.py --staged and node tools/test_image_input.mjs. Then run python tools/build_site.py in the sibling zirkomirko-site repo to sync and validate the hosted result. It owns the CSP, URL, metadata, vendor-hash and size checks. Review both repositories before committing. See SECURITY.md and vendor-manifest.json.
