Four layout defects in the clinical PDF renderer:
- Stretched lines: the built-in Helvetica is WinAnsi-encoded, so glyphs
outside it (the trend arrows the summary injects, the superscript-two in
kg/m2) resolved to the .notdef box at a fallback advance width and stretched
the surrounding words. Route every drawn string (direct text, wrapped
paragraphs, and autoTable cells) through a central WinAnsi sanitiser that
maps the offenders onto safe equivalents. Embedding a Unicode TTF so the
arrows render as true glyphs is a documented follow-up.
- The sparkline dropped each reading's timestamp and plotted on an index
axis, so a trend gave no sense of its time span. Plot points by their real
timestamp and print the first/last dates under the baseline.
- No consistent bottom safe area: scattered y > 240 magic numbers and tables
with no bottom margin let content run into the footer. Introduce a single
contentMaxY derived from the page height, footer band, and bottom margin;
every break check and every autoTable bottom margin refers to it.
- Modules tore mid-block. Add an ensureSpace guard called before each module
heading and a per-line guard in every free-text loop; give the short
titration and side-effect tables rowPageBreak: avoid.
