   Tars 2.0 — «Imprenta Riso»
   --------------------------------------------------------------------------
   La web es un cartel de imprenta risográfica: tintas planas que se pisan,
   registro imperfecto y tipografía gigante como estructura. La constitución
   completa (paleta, reglas de contraste, movimiento) está en DESIGN.md.

   Tema: [data-theme="dark"] (por defecto) = tinta negra de fondo con las
   tintas fluo encima; [data-theme="light"] = papel. El atributo lo pone el
   script del <head> antes de pintar y lo cambia el botón (js/core.js).
