This is why printed labels were illegible. Pillow uses a built-in bitmap
font when it cannot load a TrueType one, and that font ignores the size it
is asked for - at 300dpi it draws letters under a millimetre tall, which
no Text size setting could fix. python:3.12-slim ships no fonts at all.
load_font now tries LABEL_FONT, a wider list of system paths, a scan of
the font directories, matplotlib's bundled DejaVu, and finally Pillow's
scalable default. font_report() says which one won, so the pages can warn
instead of quietly printing micro-text.
render_fixed also takes a dpi, so the Dymo path draws at 300 rather than
being resampled from 313.
