CHANGE LOG
File: /var/www/html/eaglesflock.nsgia.com/static/css/library.css
Type: Page-scoped stylesheet (loaded only on /library/ via extra_css block)
Purpose: Styles for reference library index page

TUTORIAL:
All values reference CSS custom properties from nsg_variables.css
(and leafriver_variables.css overrides). Do not hard-code colors,
fonts, or spacing — use var(--token-name) so the page inherits
any future theme changes automatically.
