Accessibility fixes complete

• Read CLAUDE.md and explore repository structure
• Identify accessibility issues in the codebase
• Fix poor/cryptic alt text on photos in index.qmd
• Add image-alt fields to PI YAML files (kaiemjoy.yaml, demorrison.yaml)
• Update people-box.ejs to use image-alt field (with title fallback), matching the pattern already used in software-grid.ejs
• Commit and push changes

Changes made:

1. index.qmd — Replaced 6 cryptic alt texts with descriptive captions based on the visible photo captions:

   • "CSID 2025" → "Krista and Sam presenting at the Open Software Tools for Climate Sensitive Infectious Diseases (CSID) workshop in Kanchanaburi, Thailand, 2025"
   • "aprc4" → "Krista presenting at the Asia Pacific Rickettsia Conference (APRC4) in Penang, Malaysia, 2025"
   • "Blood donation" → "Kristen donating blood after a blood collection event for the SURFACE study in Thailand"
   • "astmh" → "Kristina presenting at the American Society of Tropical Medicine and Hygiene (ASTMH) conference in Toronto, Canada, 2025"
   • "sam dbs" → "Sam collecting dried blood spots for the SURFACE (Surveillance for Fever in Amnat Charoen) study in Thailand"
   • "ntdss" → "Krista and Kristen advocating for scrub typhus to be recognized on the WHO's list of Neglected Tropical Diseases"

2. people/kaiemjoy/kaiemjoy.yaml — Added image-alt: "Portrait photo of Kristen Aiemjoy"

3. people/demorrison/demorrison.yaml — Added image-alt: "Portrait photo of Ezra Morrison"

4. _ejs/people-box.ejs — Updated image tag to use item['image-alt'] || item.title (same pattern as software-grid.ejs)
