Accordion
Expandable content panels with white, light grey, or navy backgrounds.

KEY FEATURES:
- First panel open on load; only one panel open at a time
- Plus/minus icon swap when a panel opens
- Contained column on desktop, full-width panels on tablet and mobile
- 20px panel gap on mobile, 32px from tablet up

IMPLEMENTATION NOTES:
- Uses FxAccordion JS on native details/summary
- Closed panel colors invert against the section background
