 * One token layer (--nf-*) maps onto Bootstrap's --bs-* variables, so pages
 * keep using stock Bootstrap classes and only the tokens change. Red is the
 * single accent: #e50914 on #232323 is 2.5:1, so it is used for CTAs, focus
 * rings and selected states that always carry white text or an icon, never for
 * body copy.
