/* TalenTest kawaii-pop design tokens + utility classes (Sprint 2 Task 5).
 *
 * Extracted from the inline CSS of the live landing page so the same visual
 * system can be reused by login, parent dashboard, and other public pages.
 *
 * Color palette: warm pastel (peach #f8be9e primary, sky #70d6ff, sun #ffd670,
 * mint #bcffbe, coral #ff7096) over white paper with ink #0a0a0a borders +
 * chunky 3px outlines + 2-4px box-shadow offset (neo-brutalist kawaii).
 * Typography: Nunito (display, 900 weight for hero), Inter (body).
 * Border-radius scale: 8 / 16 / 24 / 32 / 40px.
 *
 * Body class is set per page so kawaii pages don't bleed into admin pages.
