 * RankGenius site styling, layered over the Inspinia/Bootstrap 3 theme.
 * 2026 "modern technical" retheme: distinctive type (Bricolage Grotesque display +
 * IBM Plex Sans body / IBM Plex Mono code), near-black ink, a single electric-cyan
 * accent. Base typography below applies site-wide; `rg-`/`nh-` rules style the public
 * pages. Component colors read from the CSS variables, so the palette lives in one place.
