/*
 * IBC Staff — design system
 *
 * Built from the Stitch design, but layered over Bootstrap rather than
 * replacing it, so every existing screen keeps working while the look changes.
 *
 * Only the six real tokens are kept. The export carried about forty, most of
 * them Material Design defaults the tool added on its own.
 *
 * No web fonts: the school's internet is unreliable and nothing here should
 * wait on a network round-trip.
 */

/*
 * Palette taken from the school crest and ipsck.edu.pk, not invented:
 *
 *   deep indigo-navy   the ring around the crest      -> sidebar, headings
 *   warm gold          the laurel wreath              -> brand accents
 *   maroon             the flag between the mountains -> reserved, unused
 *   #1a56db            the website's own theme colour -> buttons and links
 *
 * Gold is deliberately never a button: white text on it fails contrast, and a
 * gold "Post this run" would look decorative rather than deliberate.
