/* ========================================================================================================
   The Classlings "side list" page: what the School directory and the Admin page share (the teacher,
   14 October 2026: School directory option B, "a side list"; Admin in the same look).
   The shape is the Cup's Settings page: the page's title and Home in a column down the left, with the sections
   under the title (each saying what needs you), and the chosen section filling a tall panel on the right, so
   every list gets the full height of the window. On a phone the sections go across the top.
   Tokens are Login cards' (apps/pupil-access/app.css). Buttons, text boxes and question boxes are the shared
   controls standard (shared/css/classlings-controls.css), never copied here. Fredoka for headings, buttons and
   labels; Atkinson Hyperlegible for reading. Pixel icons from the kit only, written into the page by
   scripts/directory-inline.mjs so they are there from the first frame. Nothing here moves on its own.
   A page uses it with <body class="cla-page">.
