javascript: {
  const HOST = 'mastodon.green';
  const canonicalHref = document.querySelector('link[rel=canonical]')?.href;
  const originalUrl = new URL(canonicalHref ?? location.href);
  const parts = originalUrl.pathname.split('/');
  if (parts.length === 2) {
    /* Profile: ['', '@rauschma'] */
    const userName = parts[1];
    location.href = `https://${HOST}/${userName}@${originalUrl.host}`;
  } else {
    /* Post: ['', '@rauschma', '112728257468727280'] */
    location.href = `https://${HOST}/authorize_interaction?uri=${originalUrl.href}`;
  }
