MindSift CI & Docker Release / Build, Test in Container & Push (push) Successful in 1m48s
safeHref lets only http, https and mailto become links (Markdown viewer, outliner, legal links); javascript: and friends show as text. A middleware sets a Content-Security-Policy (scripts only from MindSift, no framing, connections only to this server), X-Frame-Options, nosniff, Referrer-Policy and a Permissions-Policy. The two inline scripts of index.html moved to files so script-src stays 'self'. The second inline script also deleted every cache on each page load, which undermined the offline start; it is gone.
