AkurAI-Platform / frontend/styles.css

Latest change 0183a48e4f75fa9dcea1bf01af89c93ddb3fe5be - Refactor platform into a polished SaaS product-suite front door by Olafur Bui

/* AkurAI Platform — SaaS suite front door. Hand-written, no build step.
   Every colour comes from the AkurAI-Framework semantic tokens
   (--bg --panel --fg --accent … defined per theme in /themes.css), so the
   page re-themes across all 17 themes. Tints are derived with color-mix —
   no theme colour is hardcoded. The single exception is on-accent label text
   (#fff), the standard pairing the framework's own site uses on accent fills. */
