Repository navigation
Extended bibliography rendering: author lists longer than 12 are collapsed by default with an expand/collapse toggle, showing co-first/co-last authors and my name. Added "under review" label and preprint/paper link distinction. Publications now sort automatically by year and are numbered continuously across sections.
Refactored navigation: extracted repeated <nav> block into _includes/nav.html using Jekyll and Liquid templating. Active link highlighting now handled via page.url instead of per-page id attributes. No visible changes.
Added Jekyll SEO tag plugin: site now generates meta tags, Open Graph tags, and structured social profile data automatically from _config.yml and page front matter.
Housekeeping: added README.md files documenting site maintenance.
