/* Roux website - one design system for every page.
 * Layout: a 1180px shell; a split hero whose right half is a working view of the Roux Industry Showcase; light
 * bands for the product story, one deep-navy band for governance; the same header and footer on every page.
 * Brand: the approved Ledger mark and colours (src/ui/brand.jsx - ink #16284A, carmine #C4124F; on dark grounds
 * ink #EDE9DF, carmine #EB2468) and the product's own typeface, IBM Plex, self-hosted (assets/fonts, OFL).
 * The site's CSP is style-src 'self' with no inline style attribute anywhere: every rule lives here.
