   Utilities
   These exist so no element needs a style attribute. That is what lets the
   Content-Security-Policy drop 'unsafe-inline' from style-src: with it, an
   HTML injection could style the page — overlay a fake form, hide the real
   one, or exfiltrate data through attribute selectors. Keep this file as the
   only source of styling; adding one style="" attribute anywhere breaks the
   policy and the page silently loses that styling.
