Subject: [PATCH 2/6] Fix PR preview being overwritten by main deployment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The quarto-publish workflow was triggering on both 'main' and 'addContent'
branches. When a PR from addContent was opened, both workflows would run:
1. PR preview workflow would deploy to gh-pages/pr-preview/pr-XX/
2. Main deployment workflow would then overwrite the entire gh-pages branch

Now the workflow only triggers on 'main' branch pushes, allowing PR previews
to persist without being overwritten.

Subject: [PATCH 3/6] Fix password protection for PR preview deployments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated auth-check.js to use dynamic path resolution instead of hardcoded
absolute paths. This ensures that:
- Main site redirects to /disasters-docs/password-protect.html
- PR previews redirect to /disasters-docs/pr-preview/pr-XX/password-protect.html

The getBasePath() function extracts the current directory path and constructs
the correct login page URL relative to the current location.

Subject: [PATCH 4/6] Inline authentication script to ensure password
 protection works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ISSUE: The auth-check.js external script was not being included in
deployed HTML pages on PR previews, causing authentication to fail.

SOLUTION:
1. Inlined the entire auth-check.js content directly in _quarto.yml
   under include-in-header. This ensures the script is always embedded
   in every rendered HTML page.

2. Added verification step to both workflows (preview.yml and
   quarto-publish.yml) that checks for the presence of the auth script
   in rendered HTML before deployment. Build fails if script is missing.

This guarantees password protection works on all deployments:
- Main site (disasters-docs/)
- PR previews (disasters-docs/pr-preview/pr-XX/)
- Any future branch deployments

Subject: [PATCH 5/6] Fix getBasePath() to handle directory URLs without .html
 extension
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ISSUE: When visiting URLs like /disasters-docs/pr-preview/pr-37/ (without
index.html), the getBasePath() function couldn't find .html in the path,
so it fell back to the default /disasters-docs/, causing incorrect
redirects to the wrong password-protect.html location.

SOLUTION: Simplified getBasePath() to handle three cases:
1. Path ends with / → it's already the base directory
2. Path ends with .html → extract directory by removing filename
3. Otherwise → assume it's a directory, add trailing slash

This ensures correct redirects for all URL formats:
- /disasters-docs/pr-preview/pr-37/ → /disasters-docs/pr-preview/pr-37/password-protect.html
- /disasters-docs/pr-preview/pr-37/index.html → /disasters-docs/pr-preview/pr-37/password-protect.html
- /disasters-docs/ → /disasters-docs/password-protect.html
