SubZeroAccordion class

SubZero 2.0 Accordion component.

Key behaviors:

  • Single-expandable: at most one section is expanded at a time.
  • Tap/click anywhere on the header toggles that section.
  • Keyboard accessible: Tab focuses headers; Enter/Space toggles.
  • Smooth motion: animated chevron rotation + animated size reveal.

Typical use cases: FAQs, grouped content, settings explanations.
