/*
 * tour.css — styles for the AgentsBooks guided tour engine.
 *
 * Reuses the existing brand tokens (var(--accent), var(--accent-light),
 * var(--accent-glow), var(--card), var(--border), var(--text)) so the
 * tour matches the red/orange platform theme on light and dark surfaces.
 *
 * Contract:
 *   .ab-tour-mask         → fixed full-viewport dim container (4 rects)
 *   .ab-tour-mask__rect   → one of the 4 dimming rectangles
 *   .ab-tour-hole         → the red/orange ring around the highlighted element
 *   .ab-tour-popover      → the step card (title, body, dots, buttons)
 *   .ab-tour-btn          → step buttons; --primary variant is brand-gradient
 *   .ab-tour-step-dot     → progress indicator dots in the popover footer
 *
 * Z-index layering:
 *   mask rects: 100000
 *   hole ring:  100001
 *   popover:    100002
 *   launcher:   9000 (below tours, above normal content)
