   discussion-components.css — Cardinal Energy Discussions
   COMPONENT STYLES — all rules scoped under the .disc class.
   Apply class="disc" to any container that renders messages:
     - #tab-discussion (project chat)
     - .disc-thread-stream (thread viewer replies)
     - .disc-thread-parent-msg (thread viewer parent)
   This guarantees styles work everywhere, in any context,
   without specificity fights or hidden-element CSS failures.
