   NTS27 — Registration twin stylesheet · redesign v1
   --------------------------------------------------------------------------
   The form adopts the redesign mock (Bricolage Grotesque, softer cards,
   live file previews, inline validation). Shared chrome tokens come from
   /assets/css/styles.css which loads first, so header/footer/base tokens
   (var(--paper), var(--ink), var(--accent-ink), var(--sage-ink)...) work.
