   shell … every page renders inside it"). A structural CRT frame: it owns the boot
   header at the top and the status line at the bottom, and lets <main> own the
   viewport between them so full-bleed surfaces (e.g. the map viewer) stay free.
   The "tube" is drawn with the header/footer keylines, not a hard bezel box. */
