/* Incus Student AI Toolkit — marketing page.
   Sibling of hrtoolkit/marketing/styles.css: same Pi palette as the product
   (selfhost/gateway/theme.py) — cream / forest green / tan — but set in a
   clean modern SANS per this page's brief, where the HR page kept Georgia.
   The stack asks for Inter/Geist and falls back to the platform UI sans; no
   @font-face and no third-party font host, same licensing + privacy reasoning
   as the product. Tokens are copied from theme.py — if the product palette
   changes, change it there first and mirror here. */
