/* Arcore Capital — hoja de estilos del sitio público.
   Identidad visual tomada de la landing de marca (obsidiana + gradiente solar,
   Space Grotesk para títulos, Space Mono para etiquetas). Las webfonts se
   autoalojan con el subconjunto `latin` (U+0000-00FF ya cubre acentos y ñ del
   español), font-display:swap y preload de la crítica: el LCP sigue siendo
   texto y no hay conexión a fonts.gstatic.com que bloquee el render.
   Sin JavaScript: los efectos son CSS puro. */
