/* ==========================================================================
   project-content.css — Orcheum CANONICAL "Project Content" page
   --------------------------------------------------------------------------
   The page a project opens into: a back affordance, the project title with an
   Edit/Delete menu, and the project's conversations as a card grid. One
   reusable, presentation-agnostic component; the host owns width and mount.

   1:1 with Figma node 547:7905 (Project content) + 547:8610 (the options
   menu). The centred 700px column and 79.5px top offset match the Projects
   Directory (projects-index.css) so the two views sit in the same place.
