   The product's documented design language (TECH_BLUEPRINT.md section 1):
   light theme, violet #7c3aed primary, marigold/emerald accents, IBM Plex
   Sans/Mono, data-dense and consulting-grade. Every token below is lifted
   from .streamlit/config.toml and src/theme.py COLORS so the Flask pages are
   visually continuous with the Streamlit pages during the migration — an
   admin must not be able to tell which app served a screen.
