/* site.css, Simple Ideas
   One stylesheet for every page (home and AI, Greek and English), so the languages
   cannot drift apart. Colours come from the logo (assets/brand/logo.svg): its blue
   #0079B4, its red square #DD1F26 (small marks only) and its greys. Type is Commissioner,
   designed with Greek as a first-class script (chosen over IBM Plex Sans from a six-font Greek
   comparison, 2026-10-22); IBM Plex Mono has no Greek, so it is kept to Latin-only strings such
   as file names. Layout language from the AI page variant F
   (sandbox/ai-services-page, 2026-10-22). */
