  /* Light theme, 2026-10-24. The dark theme was replaced because it failed as
     *structure*, not as text: its text tokens all passed AA, but every surface
     level sat inside a 1.13:1 contrast band, so cards had no visible edge on
     pages that list 211 (M.Tech) or 752 (Diploma) subjects.

     A light theme cannot lean on elevation the way a dark one does - white on
     near-white is inherently flat - so separation here comes from three things
     together: a page background genuinely darker than a card (1.24:1), borders
     you can actually see (1.74:1, up from 1.33:1), and a real shadow. Every
     value below is measured; ratios are against white unless stated. */
