/* ---------------------------------------------------------------------------
   dt-base — the standalone foundation of the redesign.

   This file exists so the purchased theme can eventually be unlinked. It
   reimplements, from the token layer, the layout and utility classes the app's
   markup actually uses — measured across the rendered pages, not guessed: the
   12-column grid, the display/flex/spacing/typography utilities, and the few
   visual helpers. Component styling lives in dt-components.css, the uploader in
   dt-uploader.css, tokens in dt-tokens.css.

   Nothing here targets a theme class by name. It is a replacement, not a patch.
