"""Build the logbook figures from the reproduction results.

Palette: categorical slots 1 (blue) and 6 (orange) from the dataviz reference
palette -- validated with scripts/validate_palette.js in BOTH light and dark
(all checks pass; worst adjacent CVD dE 24.7 protan). Text stays in ink tokens,
never the series colour. Every chart also emits its raw numbers as CSV so the
figures are auditable and machine-readable.
