/* ══════════════════════════════════════════════
   tour.css
   Interactive onboarding tour — spotlight + tooltip.

   Architecture:
   - .tour-overlay: fixed full-screen canvas that dims everything
     except a transparent spotlight cutout (clip-path inset technique).
     z-index 480 — above all celebration overlays (max 270) and
     normal modals (200), below signup (500) and onboarding slides (600).
   - .tour-tooltip: the instruction card, absolutely positioned by JS
     relative to the spotlight target.
   - .tour-pulse: faint animated ring drawn around the spotlight to
     draw the eye without being distracting.

   Reuses existing design tokens only (--gold, --gold-glow,
   --surface-deep, --border, --text-bright, --text-muted, --font,
   --font-mono, --radius-lg, --radius-sm, --radius-full,
   --space-*, --ink, --transition).

   Reduced-motion: all decorative animations are disabled.
   The overlay and tooltip remain fully visible and readable.
