The mobile link page, website, store, document citation, and design services each carried their own copy of the rule for which link addresses are safe to hand to a browser. They now share BookMeToday\Support\SafeUrl, which refuses executable schemes, credentials in front of the host, control characters, and over-long addresses. Website links keep relative paths; store tracking links accept https only.
