{# Overrides the pydata component of the same name. The stock template renders the toctree from `startdepth=1`, i.e. only the pages nested under the current top-level entry. polyxios' toctree is flat at the top level, so that leaves the sidebar empty on most pages. `startdepth=0` renders the whole tree instead, so every page shows the full documentation navigation - the landing page is the exception, and drops the sidebar entirely via `html_sidebars` in conf.py. #}
