 * Gas Gap Monitor + NMDPRA Library.

 * Matched to the Afrindustria Build materials (fundflow/web/league_table_build.py
 * and the Fund Flow Monitor decks): deep navy ground, serif italic headlines,
 * small-caps tracked labels, square corners. Sector colours follow the brief:
 * coral for power, amber for commercial, green for gas-based industries.
 * Dark only, like the parent materials.
