web/static/panels.css

/* Panel styles shared by every delivery mode: the FastAPI page, the static Space, and the
   Gradio Space. Deliberately contains NO bare element selectors (no `body`, `button`, `select`)
   and no page-chrome layout. Gradio owns the page around these panels, and restyling its
   widgets from here would fight it. Page chrome lives in styles.css (FastAPI and static) and
   gradio.css (the Space) instead.

   The panels are the four stages of a run: a row of stage cards (.stage-bar) and one panel per
   stage (#panel-plan, #panel-search, #panel-rank, #panel-answer), all inside #pipe. stages.js
   shows the panel that matches the selected card by setting data-selected on #pipe. Rules are
   scoped under #pipe so they win over the typography Gradio gives its HTML blocks. */
