/* :has() validation-state affordances (STEWARDed from the has-glow dossier

   own validation still owns Next/Submit gating and the alert messages; this
   only gives a live green/red cue on the field wrapper as it's filled in.
   :not(:placeholder-shown) is the load-bearing part: an untouched empty
   field always shows its placeholder, so it can never read as invalid
   before the parent has typed anything. input:not([type="file"]) excludes
   the birth-cert file upload - a required file input has no meaningful
   :placeholder-shown state, so without the exclusion it would read as
   invalid from first paint. --color-success / --color-error are already
   defined in both :root (css/style-01.css) and [data-theme="dark"]
