Some courts (Taiwan's ``judgment.judicial.gov.tw``, Hong Kong's
``legalref.judiciary.hk``) reject plain HTTP clients or hide the judgment
behind script/anti-bot checks, so the requests-based ``scrape_full_text`` only
captured error placeholders. This module drives headless Chromium via
Playwright, waits for the judgment container to appear, and extracts its text.
Output matches ``legex.scrape_full_text`` / ``data/<cc>/full_text.jsonl`` so the
inference step consumes it unchanged: one JSON object per line with a
filesystem-safe ``case_id`` slug and a ``full_text`` body prefixed with the
original ``case_id``/``link``.
Per-site content selectors live in ``CONTENT_SELECTORS``; unknown sites fall
back to the page ``body``. Rows whose extracted text is shorter than
``--min-chars`` are recorded with a ``RENDER_EMPTY`` marker and retried on the
next ``--resume`` run.
Usage:
uv run legex-render-fulltext --country tw
uv run legex-render-fulltext --country tw --limit 5 --headed
uv run legex-render-fulltext --country hk --resume
