   Palette and geometry are lifted verbatim from the iOS app so the site, the
   app, the keyboard and the extension read as one product:
     mobile/ios/Shared/TWTheme.swift  — the light/dark palettes
     mobile/ios/Shared/TWLogo.swift   — the monogram, the -13 degree lean,
                                        and the ombre tile gradient
   House rule from TWTheme.swift: surfaces and actions are GRAYSCALE. The gold
   is an attention colour only — it marks the recommended reply and nothing
   else. Do not spend it on decoration.
