/* ============================================================================
   src/shared/forms.css — shared Join-Us form system (.jf-*).

   Used by BOTH new pages (Become a Customer, Become an Engineer) so the two
   forms are visually identical. Injected as an extra <style> block after the
   page CSS by the assembler. Uses the site design tokens (--ink navy, --amber,
   --red) and the same fonts as the rest of the redesign. Frontend only — no
   submission logic lives here.
