/* Inequality Explorer: the base layer every page stands on.

   WHAT THIS IS. Until 12 October 2026 both base templates loaded the whole of
   Bootstrap 5.0.2's stylesheet (155 KB, static/vendor/) for the classes the
   templates still use: the grid, spacing and text utilities, the form
   controls, buttons, cards, badges and alerts (TO DO FL-098 point 4; the
   JavaScript had already left on 9 October). This file holds exactly the
   rules of that stylesheet that can match something on one of this tool's
   pages, about 30 KB with these notes, and nothing else. It is linked where Bootstrap was, in
   templates/base.html and templates/backoffice/base.html, before style.css,
   so every later sheet wins the same fights it won before.

   HOW IT WAS MADE. Every class name in templates/, static/js/ and the shared
   account pages was collected; a Bootstrap selector stayed only if every
   class it requires is in that list, and the element defaults stayed except
   for elements no page contains (pre, kbd, abbr, blockquote, fieldset ...).
   Then all 59 page states (participant screens, every backoffice page, the
   account pages, error pages) were rendered with the full Bootstrap file and
   with this one, in headless Chrome at 1440 and 375 px: the computed style
   and the box of all 13,500 elements were identical.

   THE RULE FROM HERE. This is the tool's own sheet now, not a library copy:
   no new Bootstrap class name in a template without a rule here. A new page
   uses the fleet vocabulary (backoffice-core.css: .bo-*, .btn, .field,
   .hint) or the tool's own classes in style.css. Rules here may be edited or
   deleted like any other; moving a page onto the fleet vocabulary is how
   this file shrinks.
