/* =========================================================
   Diction Masters — the shared page design system.
   Loaded on every page by base.html, straight after base.css.

   It holds the site chrome (header, footer, messages) and the pieces
   every learner page is built from, in the look first made for the
   dashboard and EchoSpell: a dark hero with breadcrumbs and a
   progress ring, then a warm workspace of cards that lift in 3D.

   Everything is prefixed `ui-`. The older app stylesheets (app.css,
   book.css, library.css, assessments.css, clash.css) still load where
   their pages need them; the "App extras" section at the bottom
   refines their components inside a `.ui` page without renaming
   anything a script relies on.
