- Line 14: Update the AutoVideo component’s autoPlay behavior to check
prefers-reduced-motion and avoid starting playback for visitors who request
reduced motion; show a still frame with an explicit play option for them while
preserving automatic playback for other visitors.
- Line 18: Update the AutoVideo component to defer both source loading and
autoplay until the video approaches the viewport, using supported video lazy
loading or an intersection observer; preload="none" alone does not prevent
autoplay downloads.
- Line 16: Update the AutoVideo component’s looping video element to expose
native controls, allowing visitors to pause and resume autoplaying videos. Keep
the existing looping behavior.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Disable automatic playback when reduced motion is requested.
autoPlay starts these demonstrations even when the visitor requests reduced motion. That leaves motion-sensitive visitors exposed to four looping videos. Check prefers-reduced-motion before starting playback, and show a still frame with an explicit play option for those visitors. (developer.mozilla.org)
Based on learnings, frontend animation must honor prefers-reduced-motion.

Provide a way to pause the looping videos.
These videos autoplay and loop, but the component exposes no controls. Visitors cannot pause a demonstration while reading the adjacent content. Add native controls or an accessible pause/play control. Automatically moving content that continues for more than five seconds requires a pause, stop, or hide mechanism unless the movement is essential. (w3.org)

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
Defer video loading until each demonstration is near the viewport.
preload="none" does not make an autoplaying video lazy: autoplay takes precedence and requires the browser to download video data for playback. As a result, the four videos can load on the initial page visit even when they are below the fold. Defer playback and source loading until each video approaches the viewport; use video lazy loading where supported or an intersection observer. (developer.mozilla.org)

Description
This PR fixes #8144
This PR introduces a proof of concept for replacing large GIF assets with optimized MP4/WebM videos in the AWS Architecture Diagram section.
AutoVideocomponent for consistent video rendering.playsInlinefor the videos./cloud-native-management/generate-aws-architecture-diagram.Notes for Reviewers
Please review the video implementation and the AWS Architecture Diagram page.
If this approach is acceptable, the same GIF-to-video optimization can be applied to the remaining affected pages.
