/* ============================================================
   PER-AGENT DEMO — shared component library
   Added 2026-04-29 — used by samples/*.html pages.

   Architecture:
   - .demo               = section wrapper
   - .demo-stage         = positioning context for frame + dots
   - .demo-frame         = stylized "device/window" chrome
   - .demo-screens       = grid stack of steps (CSS grid overlay technique)
   - .demo-step          = each individual step (one shown at a time)
   - .demo-progress      = clickable dot indicators
   - mock UI components  = chat bubbles, KPI cards, calendar slots, etc.

   Slideshow technique: all steps share grid cell 1/1 so the parent sizes
   to the tallest step automatically. Active step is opacity:1 + visible,
   inactive are opacity:0 + visibility:hidden. Smooth crossfade.

   Internal "moving parts" (typing cursor, pulse dots, thinking dots,
   click cursor) are CSS-only animations baked into each step's HTML.
   They run continuously regardless of which step is active — JS only
   controls which step is visible.

   Reduced-motion: the global prefers-reduced-motion rule already kills
   animations (line ~635). The slideshow JS also exposes all steps
   stacked when reduced motion is on (see initDemo in main.js).
