/* =========================================================
   FOOTER.CSS — Department of Arts and Culture, Meghalaya
   MeitY-style footer. Layout comes from the Bootstrap grid
   (row / col-lg-8 / col-lg-4); this file sets colours, type
   and spacing only, so it never fights the grid.

   Font sizes use the DBIM v3.0 tokens from style.css (--dbim-fs-*),
   so they follow the desktop/mobile type scale and still grow with
   the A+ buttons. Line heights are unitless so they grow with them.

   Markup: components/footer.html
   Background: #771D1D (key colour) — white text ≈ 11:1
