+"""いじめ重大事態対応フロー図の印刷用PDFを、SVGからベクターで生成する。
+
+以前は 2.5 倍のラスタPNGを埋め込んだPDF（1ページ版 約2MB / 6ページ版 約4MB）を
+使っていたが、同じレイアウトのままベクターで組み直し、大幅に軽量化する
+（各ファイル約200KB。文字は拡大しても綺麗）。
+
+- A4縦・タイル分割版（2列×3行＝6ページ、のりしろ重複あり）
+- A4縦・全体像1ページ版（縮小・見取り図）
+
+レイアウトは旧ラスタ版と同一（A4 3100x4382px 相当、余白100px、紙面2900x4182px、
+タイル 1160x1672.8、列 x=[0,660]、行 y=[0, base/2, base]）。
+base は SVG の元の高さ（リンク行を追記する前の値）。SVG の末尾に追記した
+解説ページへのリンク行は、PDFではフッターのリンク注釈として付ける。
+
+使い方: python scripts/make-flow-pdfs.py
