/*
 * AI Coding Kickstart by Axonova — one hand-written stylesheet. Phone first (390px).
 *
 * A sibling of axonovatechnologies.com: the same indigo, slate and coral, the
 * same Space Grotesk / DM Sans pairing, the same rounded geometry. What is
 * ours: the live batch. A ticket-like batch card with a seat map of the real
 * seats, and one deep-indigo band holding the Sunday timeline. Caveat (the
 * Axonova handwriting) appears only where a teacher would write by hand: the
 * margin notes on the prompt recipe and the signatures on the certificate.
 *
 * Type: Space Grotesk (headings), DM Sans (reading), DM Mono (code),
 * Caveat (handwriting). All self-hosted, latin subset, OFL (fonts/OFL.txt).
