 * Site de Deepslate — portage statique de la maquette Claude Design.
 *
 * La maquette est un composant `.dc.html` : du React, un runtime de 70 Ko et
 * des styles en ligne. Ici c'est du HTML servi par notre serveur Rust, donc
 * tout est repris en CSS classique — meme identite, sans framework a charger
 * avant le premier rendu.
 *
 * Direction reprise telle quelle : fond presque noir, degrade turquoise vers
 * amethyste reserve aux actions, chasse fixe pour les etiquettes, Silkscreen
 * pour les reperes numerotes. Les cubes flottants font le lien avec le jeu.
