/*
 * Design foundation taken from the Lovable prototype (discover-ua.lovable.app).
 * Tokens and base components only; pages opt in by using the ds-* classes,
 * so nothing here changes existing pages until they are migrated.
 *
 * Colors are the prototype's oklch theme converted to hex.
 * Fonts: the prototype names "UA Brand" but never loads it, so what renders is
 * Figtree (text) and Onest (headings) from Google Fonts.
 *
 * Font sizes are always em (never rem/px): the accessibility menu scales text via
 * font-size % on #page's children, which only em-based sizes inherit.
 *
 * Optical centring: in single-line buttons/pills Figtree renders ~1px above the
 * centre, so they take 1px more padding on top than at the bottom
 * (calc(x + 1px) / calc(x - 1px)), or padding-top: 2px when the height is fixed.
 * Keep that convention for new buttons.
