   DIAGNOSIS FIXES — from the live visual review, 2026-11-14
   The old block theme squeezed everything into a ~660px column,
   cards were 170px emoji tiles, tool pages had ~180px dead space
   and a duplicated heading, ad boxes looked broken, and the
   header/footer were bare defaults. These rules fix that.
