/*
  redKAOS.net man indexes — index.css

  Used only by src/templates/getIndex.php for the home (/) and the
  section indexes (/man1/ … /man8/). Individual modern man pages keep
  using man.css (the "Modern chrome" terminal-fidelity stylesheet);
  LuCAS legacy .html pages keep oldman.css. This file lives outside
  the "terminal fidelity" doctrine of IDENTITY.md because the indexes
  are navigation pages, not man-page content.

  Palette and typography mirror redkaos.net + redkaos.tools so the
  three ecosystems share the same visual language.

  Fonts autohosted under /style/fonts/ (subsetted Spanish + English):
  - Nimbus Mono (TeX Gyre Cursor) — h1 marquee
  - Ubuntu                         — body prose, comment text
  - Ubuntu Mono                    — command names, h2, code
