Charts:
- Shrink axis label fonts and thin/space x-axis labels by actual pixel
spacing so dense or long labels no longer overlap.
- Line tooltip shows only the point nearest the cursor instead of every
series stacked vertically.
- Hovering a legend entry highlights its element: bar/line series fade the
others (pie expands the matching slice), in app and presentation mode.
- Add optional min/max threshold lines per bar/line chart (ignored for pie),
editable in the chart editor and drawn in both the live preview and the
exported SVG.
Theme:
- Resolve relative logo paths in a ThemeProfile against the project path and
home directory so deck logos load regardless of working directory.
Tests cover bound round-trip, editor fields, SVG bounds, legend-hover fading,
and bound-line rendering.

New "Grafiek" slide type rendering bar, line and pie charts.
Storage fits Marp: a ```chart fenced block holds the spec as JSON. Small
charts keep their data inline (the .md stays self-contained); data-driven
charts link an external CSV via "source": "data/<name>.csv" kept in a
separate data/ directory and packaged into .ocideck like images. On save
the inline data is stripped for linked charts (the CSV is the source of
truth); on open it is re-hydrated from the CSV.
- lib/models/chart.dart: ChartSpec/ChartSeries JSON parse/serialize,
inline-vs-source handling, and a CSV parser.
- In-app rendering (preview/presenter/PDF/PPTX) via fl_chart.
- HTML export renders charts as self-contained inline SVG generated in
Dart (no JS chart library); export inlines linked data so the page is
standalone.
- Editor: type picker, title, a CSV-style data field, and CSV import that
can inline the data or link it as data/<name>.csv (with unlink).
- Markdown round-trip + .ocideck packaging of linked CSVs; translations
for all supported languages.
flutter analyze is clean, all tests pass (new chart/CSV/round-trip tests),
and the macOS debug build compiles.
