/* Kairo website, dark system (October 2026).
   Colours come from the app's Theme.swift (graphite surfaces, Kairo blue
   accent, logged green). Display type is Fraunces; body is the Apple system
   face with Inter elsewhere. Every page loads only this file and kairo.js.
   Contrast (WCAG): --text-2 8:1, --text-3 ≥4.5:1 on every surface,
   --link 6.7–8.3:1. White on #5B8DEF fails (3.2:1), so accent buttons use
   dark text. */
