/* ==========================================================================
   dulus.ai — fuel.css
   /fuel/ only, loaded after dulus.css: the receipt hero, the six-step proof
   chain with its sticky index, the rates table, the holder free tier and its
   balance slider, the token and its click-to-load chart, Fuel versus your
   own keys, the questions and the closing band. Every class starts fuel-.

   Artifacts (the mono panels next to each step) are real text, not images:
   crisp at any DPR, selectable, translatable. Sample values are marked as
   such in their header and never show a charge next to a token count, so no
   absolute rate can be read off the page.
