/* ============================================================================
   Replay viewer guided-tour engine — visual styles.

   Class prefix .rv-tour-* is part of the engine's public contract; do not
   rename.

   Theming reality: the popover mounts to document.body, which sits outside
   the #page-dashboard scope where the design tokens (--accent, --text-*,
   --border-strong, etc.) are defined. Every var() in this file therefore
   resolves to its hardcoded fallback at runtime. The fallback values are
   intentionally chosen to match the dashboard tokens (#56c2ff accent,
   #f4f6fa primary text, etc.) so the tour looks native to the replay
   viewer. The var() references are kept as forward-compat hooks for the
   day someone migrates the tokens to :root.

   Sole exception: --border-strong in #page-dashboard is #2f3742 (neutral
   steel). The tour deliberately wants accent-blue border to match its own
   visual language, so border-strong references are written as literals
   below — not as var(--border-strong, …) — to avoid surprise if/when the
   tokens move to :root.
