/* ════════════════════════════════════════════════════════════════════════
   study-page-spaces.css: named Spaces and the All view on the Space home
   (public/js/study/study-page-spaces.js and study-page-files.js, drawn by
   study-pages.js). Loaded after study-pages.css, so it borrows that file's
   rows (.sp-row, .sp-ico) and tabs and only adds what is new: the shelf of
   Spaces, one Space's screen, the Source column and the file rows.
   Tokens and the tactile .k-btn come from /css/shared/khio-ui.css, so light
   and dark follow html[data-theme] with nothing to redo here.
