Add duplex PDF build targets with pdftk page interleaving

- Add pdftk-java to Docker image for PDF page manipulation - Extend generate_backside() to repeat back content num_pages times so front and back PDFs have matching page counts for pdftk shuffle - Add build-duplex and build-blanko-duplex Makefile targets that combine front and back PDFs with alternating pages (front1, back1, front2, back2) - Document duplex targets in README Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Move Python generation step into Docker, no local Python required

Author	SHA1	Message	Date
Peter Adam	ca995a1c1f	Add duplex PDF build targets with pdftk page interleaving - Add pdftk-java to Docker image for PDF page manipulation - Extend generate_backside() to repeat back content num_pages times so front and back PDFs have matching page counts for pdftk shuffle - Add build-duplex and build-blanko-duplex Makefile targets that combine front and back PDFs with alternating pages (front1, back1, front2, back2) - Document duplex targets in README Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 16:16:20 +02:00
Peter Adam	f811c3fd80	Move Python generation step into Docker, no local Python required Add python3 and python3-yaml to the Docker image so generate_cards.py runs inside the container. Both the generate and build-blanko Makefile targets now use docker run instead of a local python3 call. Remove Python/PyYAML from the README prerequisites.

Peter Adam	b22f1f74a8	Increase card height to 9.5cm, add printer margins, and fix second card placement - Extend card bottom from y=-7.2 to y=-8.2 (8.5cm → 9.5cm per card) so the second card naturally lands in the lower half of the page - Increase all margins from 0.4cm to 0.6cm for printer compatibility; scale front tikzpicture x-axis to 0.990cm to compensate for narrower printable width - Increase back side row height from 2.833cm to 3.167cm (matching new card height) and reduce column width from 7.0cm to 6.9cm to fit within new margins - Reduce inter-card vspace from 0.8cm to 0.6cm to prevent second card page break Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 14:32:43 +02:00
Peter Adam	f2eda5bf43	Add brevetkarte-blanko.tex to gitignore and clean target Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 09:35:34 +02:00
Peter Adam	a2b5c6dc4a	Add blanko build target, fix preamble duplication, update event config and margins - Add --blanko flag to generate_cards.py for blank cards (no CSV needed), 2-up layout - Fix preamble duplication bug affecting both blanko and multi-participant personalized builds - Add make build-blanko target; default make now builds personalized + blanko - Reduce page margins from 0.8cm to 0.4cm for Kyocera P6026 - Widen tikzpicture columns (6.9→7.2cm) and tabular columns (6.6→7.0cm) to fill page width - Update event.yml for BRM400 Bonn–Lüttich–Bastogne–Bonn, 9. Mai 2026, with 6 controls Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 09:33:04 +02:00
