/* --------------------------------------------------------------------------
 * site.css — first-party base styles for Tynker on Django.
 *
 * Framework-free (no Bootstrap/Tailwind). Provides:
 *   1. Design tokens (a playful purple / teal / orange kid-brand palette).
 *   2. Product chrome: sticky header nav + multi-column footer.
 *   3. The marketing landing page components (hero, course cards, steps,
 *      audience cards, stats band, CTA band).
 *   4. Legacy helpers still used by the /dev/ status dashboard and the bare
 *      auth pages (.card, .checklist, .badge, .lede, .errors, ...).
 *
 * All artwork is inline SVG in the templates; this file only handles layout,
 * color, and type. Loaded via {% static 'css/site.css' %} (hashed in prod).
