/*
 * KTBG admin — shared design tokens + components.
 *
 * Linked by every admin surface (admin.html, enforcement.html, schools.html,
 * editor.html) so they look and behave like ONE product instead of three.
 * Page-specific rules stay in the page; anything shared belongs here.
 *
 * Contrast targets: body text >= 4.5:1 on its surface, UI boundaries and focus
 * rings >= 3:1. --line is a meaningful border; --line-soft is decorative only.
