"""SSR-specific tests for the Muse Hub repo settings page.

Verifies that the settings page uses server-side rendering (Jinja2 templates)
rather than a client-side JS shell. The handler passes ``RepoSettingsResponse``
into the template context so field values are embedded in the HTML at
render-time — no client-side fetch required to display the form.

Test matrix:
- test_settings_page_renders_repo_name_server_side — GET page, assert repo name in form value
- test_settings_page_general_form_has_hx_patch — general form has ``hx-patch`` attribute
- test_settings_page_danger_zone_has_hx_delete — delete form has ``hx-delete``
- test_settings_page_section_nav_present — section nav links present
- test_settings_unknown_repo_404 — unknown slug → 404
