/* ==========================================================================
   TRIPLA — Simplified, Commented, "Cosmic" UI
   Notes:
   - Duplicates removed (.btn--primary, .icon-btn, .hero, body.cosmic::before).
   - Section headings fixed to render gradient text correctly.
   - One hover/elevation system for cards, forms, and primary buttons.
   - Keep this file as single source of truth.
