"""Tests for HTMX infrastructure — static assets, base.html wiring, and helpers.

Verifies that:
- htmx.min.js and alpinejs.min.js are present in the static directory.
- base.html includes the correct <script> tags and hx-boost attribute.
- musehub.js contains the HTMX JWT auth bridge and after-swap hook.
- The is_htmx() / is_htmx_boosted() helpers return the correct values.
- The static files are reachable via the /static/ HTTP endpoint.
