/* ============================================================
   GPW — Forms component (RFQ + future forms)
   ------------------------------------------------------------
   Promoted from the inline EMS RFQ styles (Issue #05) so the
   unified Request-a-Quote and any future form share ONE
   brand-locked, accessible component.

   Brand rules enforced here (see styles.css tokens):
   - Primary action = coral fill + INK text (never white on coral).
     The submit button uses .btn.btn--primary for color/contrast;
     this file only adds layout, never overrides its color.
   - Focus ring = teal (--focus-color), 3px, offset 2px.
   - Lato for controls; group eyebrow in Lato (Trirong removed in #19).
   Loaded AFTER styles.css / utility-bar.css and BEFORE
   global-nav.css so the nav delta still wins the cascade.
