/*
  File role: the look of the knowledge library (/ro/knowledge-library/).

  Identity comes from the site, not from this page: the dark #001120 and the ember #E4812F are the ones /ro/ and
  /ro/e-reg/ use, and so is their split: ember on actions and focus, the dark navy on what is selected. No green
  (on /ro/e-reg/ it only marks "included"). The greys are the tokens of general/styles.css (:root), the typefaces
  the global Inter Tight + Inter. Corners are 7px (code-writing rule 11); chips stay pill-shaped.

  Everything is scoped under body.kl, a class only this page carries, so no rule written here can reach the shared
  header, the footer or another page.
