/* viralizi.ai landing — page layout. Built from prototipos/landing-template.html */
/* Layout: dark-first landing, 1200px column; noite sections for impact, gelo sections (data-theme="gelo") for reading.
   One orchestrated moment: the hero capture (mesh face scanned inside the logo's focus brackets, event cards springing in).
   Tokens below are compiled from the viralizi.ai design system (tokens.json); the page commits to its own two themes. */
