/* ---------------------------------------------------------------- * premium-backdrop.css — the site-wide page background. * * Single source of truth for every page's backdrop. Replaces the old * per-page slate fills + floating-orb radial gradients with one * uniform, premium "deep navy" surface: * * - a deep navy base (#060a17) * - a broad navy -> deeper-navy radial settle for quiet depth * - a faint top sheen so the surface reads as polished glass, * not flat matte * * The gradients are deliberately wide and centred (no localised * circles) so nothing reads as a "floating orb". Tune the whole * site's backdrop from this one file — to shift the colour, change * the four hex values below (base + the three radial stops). * * Declared with !important so it wins over any legacy inline * `body { background: ... }` rules still living in a page's
