Minimal Jinja2 + HTMX + Pico CSS UI (all CDN, no build step) that lets
a user drop a PDF, pick a registered use case or define one inline,
tweak OCR/GenAI/provenance options, submit, and watch the pretty-JSON
result come back via 2s HTMX polling. Uploads land in
{tmp_dir}/ui/<uuid>.pdf via aiofiles streaming with the existing
IX_FILE_MAX_BYTES cap.
All submissions go through the same jobs_repo.insert_pending entry
point the REST adapter uses — no duplicated logic. The REST surface is
unchanged.
Tests: tests/integration/test_ui_routes.py — 8 cases covering GET /ui,
registered + custom use-case submissions (asserting the stored request
carries use_case_inline for the custom path), malformed fields_json
rejection, and the fragment renderer for pending vs. done.
New deps pinned explicitly in pyproject.toml:
jinja2, aiofiles, python-multipart (arrive transitively via FastAPI but
we own the import surface now).
