   HACKATHON 2026 — Stylesheet v2
   Premium tech-event identity: Deep Indigo Navy + Electric Blue + Cyan
   + Purple + Magenta + Warm Orange accents.
   All class names preserved from v1 so no PHP/HTML markup changes
   are required — only values/behaviour were upgraded, plus new
   component classes were added for new sections.
