/* AI Radar Model History, in the chosen design (Claude Design handoff, 1 October 2026):
   1c Release Explorer, 1e Model Detail, 1a-style company page, 3a Model Timeline.
   Built on tokens.css (colours, fonts, company hue via --h) and pages.css (header, footer,
   .container). No web fonts, no images, no animation: nothing here needs data-motion.
   Evidence and flag colours are a second carrier only; every state is also text (§31). */
