/* ==========================================================
   IMT Hyderabad Learning Resource Centre – base layer (loaded from commonhead on every page)
   Fonts, brand tokens, the logo lockup and the four-dot motif from the IMT logo.
   "Campus Metro": warm colours from the IMT gold torch and the terracotta campus walls,
   with a deep aubergine for dark bands. The home page lives in imth-home.css + imth-metro.css;
   inner pages use the theme3 "modern" layer plus imth-app.css / imth-popups.css.
   Token names were kept from the IMT Hyderabad port so every inner stylesheet still works:
   --imth-blue* = terracotta, --imth-gold* = marigold, --imth-sky = coral, --imth-serif = the display face.
   Fonts are self-hosted (Unbounded and Plus Jakarta Sans, SIL OFL): the CSP blocks Google Fonts stylesheets.
