-- Visual identity from existing video assets: dark background (`#0a0a0f`), purple (`#9C27B0`), cyan (`#00E6FF`), glitch/scanline effects, tech-cyberpunk aesthetic
+- Visual identity: warm editorial. Oat ground `#F2E9D6`, espresso ink `#3B2619`, warm sand `#D9C7A5`, honey oak `#AC8050`, dusty navy `#29444B`, muted olive `#747552`, terracotta accent `#B76D48`. Chunky rounded display type (Fraunces), soft rounded surfaces, warm window light, matte textures. No stark white, no pure black, no neon, no cyberpunk.
+- Style authority: `/root/workspace/shared/manifesto/STYLEGUIDE.md` — read it before changing any page. Claims and voice authority: `MANIFESTO.md` in the same directory.
+- The old dark/purple/cyan video identity (`#0a0a0f`, `#9C27B0`, `#00E6FF`) is retired for web. Video title cards still needing it should be re-rendered in the warm palette rather than reintroducing the old one.
