/* lingolo.bg: one stylesheet for every page, mobile first.
   Kids edition (2026-10-14): built for children 7 to 16 and their parents.
   Calm palette (round 2): only the logo's orange (#f69220) and yellow
   (#fcb63a) with their light tints, a deep ink blue for text and the
   footer, a warm cream page. One typeface, Nunito. The old kids colour
   names (sky, mint, berry, grape) stay as tokens but now hold warm tints,
   so every block follows. Accent fills always carry dark ink text; orange
   as text uses the darker --primary so it stays readable (AA) in both
   themes.

   Layers, lowest first: reset, tokens, base, layout, components, pages,
   utilities. Later layers win without extra specificity. */
