/* =============================================================================
   Contribution: the few things page.css and engage.css do not do.
   The page carries `engage` beside `contrib` and speaks the Integrated Human
   Practices soft style (assets/css/engage.css).

   18 October 2026, second pass. The chapter tabs are gone: the seven sections
   read straight down the page, and the two things this file still adds are
     1. the board (.gl) that opens the page, one tile per contribution;
     2. the download shelf (.fset), every file on the wiki as a chip you can
        click, grouped on a pale ground.

   needs a seventh chapter colour; engage.css carries six. */
