/* SGL v2 design system. The flight-line system from v1, rebuilt on SGL's own
   colours, sampled from sgl.com (see AUDIT.md): SGL Blue #00607C, deep blues
   #003F49 / #143A4D / #1B4E67, link blue #004B7C, ice blue #B2D7E4, SGL Green
   #6C9536, bright green #84C225, neutrals #FFFFFF / #E9F1F3 / #CFCFCF /
   #686868. Flat colour only, no gradients, no blur.
   Type: Georgia, 'Times New Roman', serif for body and headings; 'Courier
   New', Courier, monospace for eyebrows, telemetry, nav labels, buttons,
   table heads, captions and readouts. Revision R3 restores this original
   system while retaining the slim six-item header nav from revision R2. */
