   `display` (e.g. `label{ display:block }`, `.some-panel{ display:flex }`)
   silently wins over the browser's built-in [hidden]{display:none} rule,
   since author CSS always beats the user-agent stylesheet regardless of
   selector specificity — the element stays visible even while `hidden`
   is set. Found this the hard way in a few components; this one rule
