 * css/site-header.css - the shared SPARKS-SIX sticky header + footer chrome,
 * ported pixel-faithfully from docs/design/SiteHeader.dc.html (header) and
 * the footer block shared by docs/design/Result.dc.html / Teams.dc.html.
 *
 * Themes entirely through frontend/css/tokens.css custom properties (never
 * redeclared here). The one local addition is the header-only dark
 * accent-ink override: the DC source hard-codes color:#fff on the
 * accent-filled buttons, which fails AA against the dark theme's silver
 * accent; the fix uses a dedicated dark ink (#06262C), distinct from the
 * general --accent-ink (#161C24) that Landing and other surfaces use for
 * their own accent CTAs.
