fix: patch landscape2 links to open in new tab

[Tushar8466]

Problem

landscape2 builds the site from guide.yml and converts Markdown links to HTML <a> tags, but has these hard limitations:

• Strips target="_blank" even if written as raw HTML in guide.yml
• Strips <script> tags entirely
• External links get extra processing that was breaking rendering and showing raw HTML in the browser

There is no way to make landscape2 output target="_blank" links — it's a built-in limitation of the tool.

Solution

Since guide.yml itself can't fix this, we patch the generated output (build/index.html) after landscape2 finishes building.

What build.sh does

1. Runs landscape2 build — exactly as before
2. Uses Python to inject a small JS snippet into the bottom of build/index.html

The injected script uses a MutationObserver — a browser API that watches for DOM changes. Since the landscape2 site is a SPA, guide content is rendered dynamically after page load. The observer detects new content in the DOM and immediately sets target="_blank" on every link.

Summary

Problem	landscape2 sanitizes and strips target="_blank"
Fix	Patch build/index.html after the build using Python
Mechanism	A MutationObserver in JS sets target="_blank" on all links dynamically
When to run	Use `

Pull request overview

Adds a wrapper build script to work around landscape2 sanitization by post-processing the generated build/index.html and injecting a small JS snippet that forces rendered links to open in a new tab (including dynamically-rendered SPA content).

Changes:

• Introduces build.sh to run landscape2 build with the repo’s standard inputs/outputs.
• Injects a MutationObserver-based script into build/index.html to set target="_blank" + rel="noopener noreferrer" on links after DOM updates.
• Makes the injection idempotent by removing the prior injected snippet before re-inserting.
