{#-
  sphinx-rtd-theme 3.1.0 removed the always-on sidebar version string. Earlier
  releases (<= 3.0.2) rendered `<div class="version">{{ version }}</div>` under
  the project name via the `display_version` option; 3.1.0 replaced it with a
  version switcher that only renders on Read the Docs hosting (the
  `READTHEDOCS or DEBUG` gate). These docs are deployed to GitHub Pages, where
  that gate is never true, so the version disappeared entirely.

  We override the theme's `sidebartitle` block to restore the classic version
  div. The rest of the block mirrors sphinx-rtd-theme 3.1.0's `layout.html`
  (pinned in docs/requirements.txt) so the logo, RTD switcher and search box
  keep working. `version` is set in conf.py (SPHINX_DOCS_VERSION or the package
  version).
