/* ============================================
   ACCORDIONS — proposed canonical (.uk-accordion)
   Replaces two collapsible disclosure systems with
   diverging visual identity but identical UX:
   privacy data-categories (.accordion-item — icon
   column, separator, chevron) and pricing FAQ
   (.faq-item — mono number, primary-active gradient,
   plus/minus toggle). The base + composable slots
   capture both flavors via orthogonal modifiers.

   The static .faq-item card grid in privacy is NOT
   covered here — that's a Q-A card layout, not a
   disclosure widget; use .uk-card instead.
