/* Amazon AI Copilot - interface v3 (Apple Human Interface Guidelines).  Source of the tokens: design/tokens.css (design/build_tokens.py, contrast checked by design/contrast_check.py).
   Layout concept (design/prototypes/copilot_v3.html): ChatGPT-style sidebar + macOS-style content + iOS layout on phones.  Glass only on the navigation / control layer; data surfaces are opaque.
   The legacy variable names (--bg2, --bg3, --muted, --c-*, --s0..s3) are kept as aliases so charts, tables and cards that the business pages build keep working until phase 2 re-lays them out. */
