- get_rating_symbol nutzt jetzt -5..+5-Skala (vorher: rating>=2 → ++, was bei rating=2 oder 3 falsche '++' gab; jetzt: rating>=4 → ++). - PDF-Tabelle nutzt 5 Klassen (rating-pp/-p/-0/-n/-nn) statt 3 (positive/negative/neutral). Heller Grün/Rot-Tint für mid-strength ratings, kräftiges Grün/Rot für Extreme. Visuell deutlich unterscheidbar. - Beibehaltung der alten Klassennamen für Backwards-Compat falls irgendwo zwischengespeicherte HTML-Reports liegen. Damit ist die v2/PDF-Konsistenz fuer NRW/18/18246 (#176) bezüglich Matrix-Symbole und -Farben hergestellt. Refs: #175, #176 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

1. Render the GWÖ-Report HTML and convert to PDF via WeasyPrint
|
||
(existing behaviour).
|
||
2. If ``assessment.link`` is a fetchable PDF URL, download it via
|
||
``httpx`` and append it after a separator page so the resulting
|
||
single file contains both the analysis and its source document
|
||
(issue #9).
|
||
|
||
The append step is best-effort: a missing/empty link is silently
|
||
skipped, network errors and parse errors fall back to a single
|
||
placeholder page so the report itself is always delivered.
|
||
|
||
``bundesland`` is forwarded to ``generate_html_report`` so the source
|
||
parlament name appears in the report header.
