"""svrnty-hermes-webui-plugin — entry point.

Called by hermes-webui's plugin loader at startup (after the env var
HERMES_WEBUI_PYTHON_PLUGIN points the loader at this module).

The loader passes a single `api` argument exposing 6 methods (see CLAUDE.md +
protocol PRD §5.1). This module's job is to wire every route + static dir +
asset injection that defines the Svrnty surface on hermes-webui.

Keep this file thin. Route logic lives in `routes/<feature>.py`. Static lives
in `static/`. The map of every upstream dependency is in CONNECTION-MAP.md
(AST-generated by scripts/ast-connection-map.py).
