/**
 * Shared stylesheet for the content / policy pages: return, shipping, and any future legal page,
 * plus the left navigation that the FAQ page also uses.
 *
 * One file for the whole cluster so the pages stay visually identical. It owns:
 *   - the page shell (.ryuk-legal-wrap / head / body / main)
 *   - the left nav (.ryuk-legal-nav*), whose current-page state reuses the FAQ multi-tab look
 *     (solid near-black fill) so the tabs and the side menu read as one system
 *   - the prose elements that sit inside accordion-inner (.ryuk-legal-p / note / steps)
 *   - the copy-to-clipboard template (.ryuk-copy*)
 *
 * Accordion mechanics come from accordion.css (.accordion--faq). Colours are the Toolkit tokens
 * from global.css (--tk-color-*), which resolve to the brand palette.
