Fix glossary references displaying as ASCII codes instead of formatted text

[Copilot]

Glossary references were rendering as ASCII character codes (66, 114, 97...) instead of readable text due to Hugo's delimit function treating single-element string arrays as character sequences.

Changes

Hugo Template (layouts/glossary/single.html)

• Added type detection to handle both string and array reference formats
• String references: rendered directly via markdownify
• Array references: iterate and display each element
• Provides backward compatibility while supporting new reference format from updated glossary generator

Python Script (content/glossary/_create_glossaries.py)

• Fixed regex pattern for citation key extraction: r'\\?\[@([^\]\\]+)\\?\]'
• Now correctly parses \[@BarnesEtAl2018\] format from Google Sheets without capturing trailing backslashes
• Removed fuzzy author-year matching (unnecessary - Google Sheet uses proper citation keys)

Context

Current glossary files contain arrays like ["Barnes et al. (2018); Tvina et al. (2019)"]. The old template's delimit call converted these to character codes. The updated template immediately fixes rendering for existing files. When the glossary is regenerated, the Python script will properly extract citation keys from the Google Sheet and replace them with full APA references from apa_lookup.json.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.google.com
  • Triggering command: /usr/bin/python3 python3 content/glossary/_create_glossaries.py (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
