/* Cost check (/cost-check/, vault DECISIONS D-60). Built from dev option D, "Steps + receipts" (_dev/cost/d.css).
   B's steps on the left, a live receipt on the right, a short two-receipt
   answer. Loads after /assets/style.css. Every color routes through the
   --r-cost-* roles below; components never name a palette token directly.
   Light end of the palette: dark is for type, not blocks. Orange is the
   hero's marker swipe and the answer heading's bar only. */
