/* Sources & AI transparency — shared by the in-app page (#lib-sources, via
   index.html) and the public /transparency.html. Type follows the library
   conventions: DM Sans .72–.8rem copy, JetBrains Mono kickers. Colours come
   from the theme tokens so the in-app page follows dark/light; the static
   page defines the same tokens in its own :root. Cards use a faint accent
   tint over --bg-card, never a flat grey fill. */
