This site

jharbourne.com is built to the standard it advertises: every push lints the code, audits each page in a real browser, and fails on any slip.

It takes almost nothing from you. The analytics are cookieless: no cookies, no local storage, no profile of you, and no fonts phoning home. A portfolio has no business knowing who you are.

The same rules run through the work: cookieless, EU-hosted analytics rather than Google’s, apps that install from the browser rather than an app store, logins only for editing, and accessibility checked rather than asserted.
