/* RoastIQ — website styles.
   Design system mirrors the app's Theme.swift: a playful "AI" look — deep
   indigo/violet base with a vivid magenta → violet → cyan brand gradient,
   glassy white-on-dark cards and heavy rounded type. Fredoka (display) +
   Nunito (body) echo the app's SF Rounded voice. Cyan is the primary action
   color; the brand gradient is reserved for "magic" moments (wordmark, hero
   highlight, badges). */
