   jaxvacua workflow / module-graph figures
   -------------------------------------------------------------------------
   Shared stylesheet for the HTML+SVG figures embedded via `raw` HTML in
   the workflow page (`intro/index.md`) and the per-module API pages.

   All rules are scoped under `.jx-fig` so the styles do not bleed into
   the surrounding Sphinx theme. Each individual figure on a page should
   be wrapped in `<div class="jx-fig"> ... </div>`.
