/* ═══════════════════════════════════════════════════════════════════════
   v9 Interested — application page, rebuilt on the v2.css/v9.css design
   system (eyebrow/display hero, hairline panels, Chakra Petch micro-labels).
   Form interaction states are deliberately gray/neutral - red only appears
   on the .err validation state so the form reads friendly, not alarming.
   The form's ids/names and /api/application.php endpoint are
   contract-locked to assets/js/interested.js — markup can change, those
   can't. This file owns the page layout plus the v9 form-field styling
   (v2.css has no shared input styles yet; .v9-field is authored here).
