/* insightCISO — site styles. Colours are the brand kit's palette; the one
   rule: on light grounds the accent is Harbour, on dark grounds it is Sky.
   Sky on a light ground measures 2.20:1 and is never used there.
   Since 7-Oct-26 the whole site is light, top to bottom, as CORE's app pages
   are (Paper is the ground): no Ink banners, so no Sky anywhere on the page.
   Drawing follows insightCISO-CORE (frontend/src/styles/tokens.css, base.css):
   cards lie flat with a 1px Line edge at 10px corners, small labels are
   tracked capitals, the frame is 1280px, focus rings are 2px Harbour. Buttons
   and inputs follow CORE's FRONT pages (Login.module.css: pill buttons,
   12px inputs), not its in-app 7px buttons -- this site is a front page. Same seven colours, same two faces, same files. */
