   Tout est portee par les tokens de public/css/brand.css : aucune couleur
   n'est ecrite en dur ici, de sorte qu'un changement de marque se limite a
   brand.css. Le prefixe .lk- evite toute collision avec le theme achete.

   Concue en mobile d'abord : les regles de base valent pour le petit ecran,
   les media queries n'ajoutent que ce qui change au-dessus.
