/* TreeO marketing pages (welcome.html, pricing.html). Static, no build step:
   these files are copied into every build as-is and served next to the app.
   The one script is /pricing.js, same-origin progressive enhancement
   (checkout wiring and regional price display); every page is fully
   functional without it.

   The marketing palette is deliberately its own, not a mirror of the app's
   src/styles/tokens.css. The page tells one story: it starts above the soil
   (pale bone, air) and goes underground at a hard soil line, below which
   everything is dark, warm earth. Four anchors carry it:

     bone   : dry, pale background for the above-soil half
     soil   : dark, warm brown for the below-soil half (never grey, never navy)
     green  : one real leaf green, reserved for Roots and nothing else
     amber  : one warm accent for money movement, used sparingly

   Colour discipline: if green shows up on buttons and charts it stops meaning
   anything. Here green only ever means "what you kept". */
