/* ============================================================================
   Vaucai — the close of the home (2026-10-08): «Explicarlo es difícil.
   Probarlo es gratis.» and «Crear mi Vaucai», the last screen of the scene.
   The sentence at the poster size of the others; the button is the one of
   «Crea tu propia IA» (the blue pill with its ring of light), but this one
   is pressed by the visitor: it rises and is swept by light under the
   pointer. The scroll is in hero-scroll.js. Without JS everything is visible
   and usable.
   ============================================================================ */

/* The close is the scene's last screen (hero-scroll.js): it lights in the
   same centre as every sentence before it. Without the scroll scene it sits
   in flow under the others, readable. The type is the close's own: Inter,
   «gratis» in the brand's serif italic, one sentence per line. */
