  Aside's own visual identity — "warm agency": deep jade + warm honey on warm
  paper, single-family Geist type. Deliberately independent of the parent
  site's stylesheet (terracotta/Cormorant Garamond) — these tokens are lifted
  straight from src/theme/{palette,colors}.ts and docs/02-visual-identity.md
  in the Aside app repo, so the web pages actually look like the app.
