   DataTools — static layout-review stylesheet
   ---------------------------------------------------------------------------
   Faithful reproduction of the live Streamlit app's design system for human
   review of page layouts. Tokens are copied verbatim from src/gui/theme.py
   (§3 color + type scale) and the component values from
   src/gui/components/_legacy.py:_DESIGN_TOKENS_CSS.

   The live app applies these styles to Streamlit's data-testid DOM; here we
   re-express the same look against clean semantic classes so the static HTML
   stays readable. Where the app uses real .dt-* classes (page header, files
   card, findings, stats) the class names are kept identical.
