/* ==========================================================
   IIT Bhubaneswar Central Library – home page (body.home-modern.iit-home)
   Loaded after home-modern.css and home-sections.css.
   Layout: slate "blueprint" hero (search console with four modes on the left,
   numbered quick-access panel on the right), sky metrics strip, collection
   modules, AI tools band, the shared showcase sections, research feed,
   about + steps, rich footer.
   Look: precise rather than soft – small radii, hairline rules, a fine grid,
   IBM Plex Mono for labels and numbers.
