/* =========================================================================
   Leading Group Limited — marketing/IR site
   Design system, modernised from the Dingli Insurance Broker brand DESIGN.md.

   Brand DNA kept: steel-blue #3267AD as the single structural accent; navy
   chrome (#224E93 header, #1B2742 footer); square 0px identity; IBM Plex Mono
   tabular figures; flat, institutional, evidence-led. Figures never animate.

   Modernised for a marketing/IR audience: a dark navy hero ground for drama,
   editorial whitespace, larger (but restrained-weight) display type, layered
   navy-tinted depth, GSAP motion, one bespoke Three.js hero. Corners stay sharp.
