   Catalogue page — companion to the Tool Wall
   --------------------------------------------------------------------------
   Reuses the wall's palette, paper texture, fonts, and back-link/masthead
   classes from style.css. Adds a denser, non-rotated card grid and a small
   filter toolbar. The first 7 categories use the same tints as the wall's
   .cat-pill so a card here looks like a card there.
