/* ==========================================================================
   AI Roadmap Demo  —  .demo-*
   Loaded by: demo.html, resume.html

   resume.html reuses the form, field and loading styles from here rather than
   duplicating them, so this file is NOT demo.html-only. Check both pages
   before changing a .demo-* rule.

   Perceived-speed work matters here: generation takes ~10s, so the page shows
   structure immediately rather than a dead spinner.
