/*
 * Custio landningssida – formgivning.
 *
 * Alla färger definieras som CSS-variabler på :root (ljust läge) och skrivs
 * över under prefers-color-scheme: dark. Komponenterna använder enbart
 * var(--...), aldrig hex inline. Kontrasten är kontrollerad mot WCAG AA i
 * båda lägena (se scripts/check-contrast.mjs).
 *
 * Primärfärgen #5D6BFF är Custios varumärkesfärg (samma theme-color som
 * Custio CS). Eftersom den inte når 4,5:1 mot vitt används en något mörkare
 * variant (--brand-strong) för knappar och länktext i ljust läge, och en
 * ljusare variant i mörkt läge.
