/* НЕОН — the AI-course treatment, built from the Learn.ai reference.
   The opposite of Чертёж and of Аркада: nothing here is a physical object.

   What carries it:
   - the ground is a journey, not a colour. Near-black at the masthead, saturating to
     indigo by the footer, so scrolling feels like descending into the thing.
   - surfaces are glass: a few percent of white over that ground, one hairline border.
     No fills, no hard shadows, nothing seats when pressed.
   - type is light and large and sentence case. The page never raises its voice.
   - one accent, periwinkle, used for state and for the single warm spark that is the
     child's own action. */
