/* ============================================================================
   PJSK Viewer — UI styled after Project Sekai: Colorful Stage
   ----------------------------------------------------------------------------
   Design DNA (derived from the official app + colorfulstage.com + pjsekai.sega.jp):
     · Bright, light background — soft sky/cream gradients with confetti motifs
     · Pop-flat surfaces: white cards with very soft shadows + rounded corners
     · Pill-shaped buttons, white with a colored leading icon
     · Triangle (▲) confetti background pattern in pink/cyan/mint
     · Rounded gothic typography (M PLUS Rounded 1c / Zen Maru Gothic)
     · Pink accent (#ff5fb1-ish) used sparingly for emphasis
     · Unit identity via colored "seal" chips on the side of each card
