/* Cookie consent banner — bottom-anchored sticky band.
 *
 * Monochrome, Inter, narve tokens throughout. Two equal-weight choices
 * (Accept = solid black / interactive-bg, Decline = ghost outline) so
 * neither button is dark-patterned. 44x44 minimum tap targets per HIG.
 * Mobile (<=640px) goes full-width with a stacked actions row.
 *
 * Lives on every site-wide page via pwa_middleware until the user makes
 * a choice (recorded in the narve_consent cookie). Position is `fixed`
 * so it stays anchored to the viewport bottom without affecting the
 * document flow / scroll height. env(safe-area-inset-bottom) keeps it
 * clear of the iOS home indicator.
