"""SSR tests for the MuseHub new repo creation wizard (issue #562).

Validates that the wizard form is rendered server-side via Jinja2 — license
options, form inputs, and HTMX attributes appear in the raw HTML response
without requiring JavaScript execution.  Also validates that the availability
check endpoint returns an HTML fragment when called by HTMX.

Covers:
- test_new_repo_page_renders_license_options_server_side — license <option> in HTML
- test_new_repo_page_has_hx_get_on_name_input — name input has hx-get attribute
- test_new_repo_page_has_visibility_inputs — Public/Private radio inputs in HTML
- test_new_repo_page_form_renders_without_js — form element in SSR HTML
- test_new_repo_page_has_hx_indicator_on_name_input — hx-indicator attribute present
- test_new_repo_page_has_name_check_indicator_span — indicator span exists in HTML
- test_new_repo_name_check_htmx_returns_available_html — HTMX → HTML span "Available"
- test_new_repo_name_check_htmx_returns_taken_html — HTMX → HTML span "taken"
- test_new_repo_name_check_json_path_unchanged — no HX-Request → JSON response
