/* NigeriaAnalytics — public election site.
 *
 * Institutional register: near-black ink, disciplined green brand accent,
 * a full-bleed ink hero band that carries the headline figures, sans-led
 * display type with real weight contrast, FT-style data tables.
 *
 * Still no webfont, no framework, no build step. This page arrives on phones
 * over Nigerian mobile networks; a 40KB display face would be paid for by
 * every one of those readers. Segoe UI Variable / SF / Roboto at weight 800
 * with tight tracking carries the display work instead, and the identity is
 * carried by layout, the green, and the ink band — not by a font file.
