/* ============================================================================
   PHOENIX SUMMER CALENDAR — STYLES
   ----------------------------------------------------------------------------
   Design notes:
     • Summery palette: sky blue, sunshine, coral. Clean white cards.
     • Subtle theme cues: a sunshine glow in the header, a "rollercoaster" wavy
       divider, and a Rubik's-cube 3×3 grid in the header logo.
     • Mobile-first: day cards stack on phones, become a 7-column grid on wide
       screens. Generous spacing + large readable type.
