/* ====================================================================
   PROJECT DETAIL PAGE — individual project write-ups.
   Used by _template-project.html and every page copied from it.

   Layout: a two-column grid — a scrolling main column (write-up, blog,
   patch notes, screenshots) and a STICKY sidebar of key specs that
   stays in view as you scroll.

   Shares CSS variables from style.css and the .res-badge base from
   resources.css (both are linked on the project pages).
