+"""Repair text overflow in generated/static book SVGs (in place).
+
+Most figures under images/ are produced by the gen_chN_figs.py scripts (which
+now self-correct via svg_lib.SVG.render), but several sets — fig0-*, fig6-*,
+fig7-*, the multimodal fig9-*, and fig10-* — are static SVGs with no live
+generator. This tool applies the same width model (svg_lib.fit_overflow) to any
+SVG on disk, shrinking only the font-size of text runs that spill outside their
+containing rectangle or the canvas. It is safe (positions are never moved) and
+idempotent (re-running makes no further changes).
+
+Usage:
+    python3 fit_svg_text.py                 # fix every images/*.svg
+    python3 fit_svg_text.py images/fig6-3.svg ...   # fix specific files
