/* Hide every "Sign up" / "Create account" affordance Mastodon renders.
   Registration is via Keycloak SSO only — clicking these otherwise leads to
   the confusing "Creating an account on social.sdatown.com is currently not
   possible" page. The three locations Mastodon's React UI renders these:
     1. header.jsx          → top-right header `<a class="button">`
     2. sign_in_banner.jsx  → persistent sign-in panel `<a class="button button--block">`
     3. interaction_modal/  → "Not on Mastodon?" CTA `<a class="link-button">`
   `a[href*="sign_up"]` catches all three regardless of class changes. */
