/* ============================================================
   B.Tech — cards, grid and the homepage teaser band.

   These colleges carry no verified fee/seat/cutoff data, so the card is built
   around labelled rows (affiliation, route) rather than the four-up numeric
   fact grid used by .college-card. Same navy/gold system, different content
   shape — do not merge the two.
