/* Border-box reset — without this, `.auth-input { width: 100%; padding:
   0.75rem 0.875rem; border: 1px }` renders ~30px WIDER than its container
   because the browser default is content-box (padding/border add to width
   instead of being subtracted from it). Symptom: form fields look flush-
   left but spill past the right edge of the card. Auth pages have no other
   CSS reset (no Tailwind preflight here) so this needs to live in auth.css. */
